I think the proper solution is probably going to vary a lot depending on use case. Just full_name is probably a good default. Reconsidering whether you actually need to store a name, or whether you need more than an “informal” name is another good default. I’ve scare quoted “informal” because what you probably mean is somewhere between “preferred conversational” and “legally identifying”, and people may prefer to use a name they’ve chosen in formal settings (my understanding of Xe’s article suggests xer do [and sorry if I’m misrepresenting that, or misusing xer]). I have used a chosen name (originally chosen by a friend) for almost 20 years, both in formal and informal contexts. And many many people do, even from childhood (eg choosing to go by a middle name or a specific variant of the name on, say, their birth certificate). If for whatever reason you need or have a good reason to ask for/store a “formal” name and a “preferred conversational” name, those are probably reasonable default names, though you may want to also allow for multiple “conversational” names, and without qualification that can get ambiguous very quickly (which loops back to “reconsider” IMO).
