It's important to note that a lot of the Xianxia/Cultivation quests here (and elsewhere) have one enormous difference from the vast majority of xianxia stories:
They're sect quests.
What I mean by this is that the entirety of the quest is anchored to one spot/location and the political structure of the sect. It is true that most xianxia stories will have periods where they join a sect (or 'the court', or live in a city, or whatever), but events will conspire to have the sect invaded/destroyed by enemies, or the MC will get chased out because they offend the Grand Elder's nephew or whatever.
The point is that traditional xianxia stories are about travelling adventurers; the MCs travel throughout the realm(s) finding cool materials, loot and techniques to power them up, and then moving onto the next location. Rinse and repeat. The sect quests (e.g. Forge/Threads of Destiny, The Path Unending, etc) do not follow this story format at all, for better & worse.
In terms of xianxia recommendations; my two 'go-to' recs are World of Cultivation and Seeking the Flying Sword Path. Both of these have completed translations, so it is possible for a full read-through and I think are suitable for the first-time xianxia readers.
These two stories will introduce you to the general themes, mythologies and aesthetics of xianxia quite well. I would also rate them generally low on the sexism/racism/homophobia/genocide/psychopath MC metrics that causes the majority of xianxia to be utter dreck.
Another outside introductory xianxia would be something like True Martial World which is passable. An 'advanced' xianxia is Way of Choices (also known as Ze Tian Jin) which is excellent, but vastly unlike any other xianxia out there.
