So, let's have a bit of analysis of the leading options!
[] Bow
The ranged option, and the one everyone seems to want. It beats the knives we've currently got at long range combat, but its specialization makes it useless up close, where the knives are still useful. On the whole, a good choice of primary weapon - if you have a backup plan for when they get into melee range. If you don't have a good grounding in melee, though, you're going to have a bad time against anyone with the ability to close unless you can take them out very rapidly.
That said, however, it's especially good for ambushes when combined with stealth, and its armour piercing neatly solves our main weakness right now.
On the whole, this weapon benefits from being paired with a specialized melee weapon, and projectile and damage enhancing combat arts, but it's good for us.
[] Unarmed
Well, its main draw is that it can't be taken away from you and never truly becomes obsolete - as its dv improves with your skill, unlike every other choice, as long as you invest time into it, it will remain relevant. On the other hand, while it's never truly obsolete it's similarly never truly great, as its damage is capped by cultivation (as cultivation level caps skills, and unarmed skill caps damage), so we're likely to be outperformed by our peers, and I'm not sure about the status of damage enhancing gauntlets/gloves.
It avoids us the cost of upgrading and altering weapons, but, really, it's the same problem as the knives - you sacrifice damage output for convenience, and as a result you get a mediocre weapon, at least compared to more specialized weapons. On the other hand, damn near everyone has hands, so unarmed focused arts are likely common as muck.
Though, speaking of being common, it is a peasant's weapon. No, really - choosing it as our main melee is going to get us sneered at. Not sure we really care about that, but it's worth noting.
Not a bad choice, but... eh. Actual weapons beat it where it matters.
[] Heavy Polearm
I'm honestly not sure what this is supposed to be. I mean, do you guys mean a guandao? I'm just going to assume you do.
Decent choice, a bit atypical, but it's a specialized melee weapon so it's going to be good at melee. Probably a high damage choice, given the weight of the weapon, and it's supposed to be good at fighting a lot of enemies at once - sweeping attacks, constant movement, and such.
So, if you pair it with the bow you've got a single target ranged weapon, and a melee weapon that's good at dealing with being mobbed. I actually like this choice.
On the other hand, it's main weakness is that we might struggle in duels when compared to a a more traditional weapon like the jian, and it might not have many arts specifically focused on it due to its atypicality.
On the whole, I'm kind of liking the options that bow/guandao gives us. I'm a little sad that the Dao hasn't gotten any love, as it's not a typical Xianxia protag weapon, but it's nevertheless a solid and culturally acceptable weapon, but fuck it, let's swing a sword on a stick around.
