Beastmen in WFB are in a bit of a weird position, in that a fair chunk of their lore more or less has to be lies.
Like we keep maintaining that they're barely-intelligent beasts who hate civilization and all it's trappings… but they have metal armour and weapons, enough booze that centigors are famous drunkards, and they use chariots.
I mean, it depends on how you interpret the lore around them?
If you consider them an independent entity, disconnected from other factions, then a lot of that dismissal and hatred of civilization falls under a specific definition of civilization where anything beyond rule of strength and a complete inverse of what the different humanoids hold up, such as kings, rule of law, etc. Most of them claiming arms and armour comes through raiding and taking from the smaller villages wiped out by what few gathered herds there are, or being created by those creatures that are lesser on the hierarchy within the Beastmen herd, like Ungors and mutants taken in by the herd turning their talents towards serving the greater herd. It's like how the majority of how the Beastmen feed themselves can be tied to the efforts of female Beastmen, who act as mass grazers and scavengers, collecting food and gathering resources in service to the larger herd, including finding outcast human-born beastmen children.
That said, if we consider them as part of the wider setting, then them getting a lot more supplies and equipment by way of every other major chaotic group settling deeper into the interior makes much more sense. Lore-wise, mutants and other bands of chaos-touched individuals absolutely do exist and trade with other chaos-aligned factions like the Beastmen. Of course, they're also just as likely to get attacked and raided by the Beastmen herds as the regular human settlements, but the interaction between chaotic groups is likely to be much greater than if we treat every group as individual.
Besides, if the world was normal, Beastmen straight-up wouldn't exist at all. We gotta account for the fact that them existing is a spiteful joke being made to the existence of civilization by way of the Chaos Gods, who just straight up roll the dice and say fuck you on a 1, now go have a horrible nightmare cannibal baby who we will deliberately drive to rape, murder and kill because lol.

FFXIV has a long history of "Beast Tribes" only being seen as irredeemably violent and unable to integrate with "civilised" folks too. Hence the moniker "Beast Tribes".
The Warhammer Fantasy world strikes me as no different. There's the folks who have cities - Humans, Dwarves, Elves - and those who do not - Orks, Ogres, Beastmen. The latter are seen as fundamentally violent, yet they have as much of a society and are as much individual people as the former.
I excluded Skaven here - they have cities of course, though they are of course secret and so on. But clearly the greater factor is that Skaven society is inherently violent. Most of that violence is directed inwards, it is an utterly atrocious society to live in. We have zero examples of a Skaven outside of such a society, so we have zero reason to assume that it is inherent to their nature.
I also excluded Lizardmen, who also have cities. Because there the claim is in-universe that they are programmed by the Old Ones to be essentially living automatons. I find it rather uninteresting to give full credence to that claim - there is plenty of room for someone to have a pre-defined role, and still be a person capable of growth (even beyond that role) within that, after all.
Do note that the WoL has plenty of experience with societies she can't trust because they are fundamentally fucked up, and that this does not prevent her from feeling compassion for people in said society (at least our WoL, assuming the same for Maugan's). And that said experience is being taken into dealing with Orks, Beastmen, and otherwise here.
I think it is important to recognize the difference between Beast Tribes in an FFXIV context, and the Destructive species that exist within the Warhammer setting. The problem is that, unlike the Beast Tribes, the various destructive species within Warhammer suffer from specific issues based on their physical designs.
To make a comparison, look at the differences between the physical make-up of a Warhammer Ogre in comparison to a FFXIV Amalj'aa. The Amalj'aa have predispositions towards a heavily carnivorous diet, are specifically adapted to thriving in more arid environments such as deserts and plain environments, which means that they thrive in these environments and compete with groups like the Miqo'te Seekers but can actually be moved to comprise and work with those different groups. But if we were to compared them to an Ogre, they don't suffer the literal issues of physiology where their bodies are constantly in a state of hunger. This doesn't mean that ogres can't be very smart, intelligent and capable, but their very existence as an incomplete species due to their unfinished nature as a creation of the Old Ones means that the importance of food within their society is a fundamental that cannot be altered, and it's what plays such a massive role in their existence within Warhammer Fantasy.
Another comparison would be the Orks in the current setting, and their future incarnation within Age of Sigmar. We know, definitively, that the Orruks can actually be enticed to work alongside other species such as humans or duardin, can actually form long form friendships and connections with other groups. But we know that, definitively, that groups like the Orruks return to conflict as the ultimate arbiter of their lives, mostly because they actually need to fight and die in order to breed in the first place, but also because they derive the same levels of enjoyment from fighting as much as humans would living their regular lives.
Hell, even a Skaven could theoretically be made 'good', but you'd need to remove them from their environment and instead place them in one that exists in complete abundance, because their own physiology (specifically the black hunger) means that they are consistently at odds with their own constant cycle of breeding, destroying their environment in ravenous hunger, then being forced into conflict with everything around them in order to simply exist.
Yeah, I fully expect that compassion that appears in the Beast Tribe quests, but a lot of the issues around dealing with these groups in Warhammer is that their literal physiological make-up drives them into that inevitable conflict (Skaven, Greenskins, Ogres), or their existence is deliberately propagated by a directly spiteful sect of gods, without whom they literally would not exist as an actual species (Beastmen, Mutants, assorted Chaotic groups).
I'm not that familiar with Warhammer so apologies in advance if this is completely wrong, but I was under the impression that violent conflict was one of the primary methods the Orks used to spread their spores?
It depends on which edition, and whether you want to use 40k lore as well. Old lore had them be marsupials and raise their young in a pouch from which they burst out once their big enough, but this was considered too silly and they were instead changed into basically being a fungal system for Fantasy, Age of Sigmar and 40k.
Basically, Orkz fight and die, release spores upon death which turn into fungal growths, from which grots, squigs, mushroom growths and everything else needed to sustain the newborn 'yoofz' grows, and then they eventually grow up from (funnily enough, on occasion an Ork will pop out of the earth with the mushroom cap still growing out of their head, providing them with an easy first meal), then start going around getting in fights to breed more.
