Figuring out identity I think boils down to figuring out what gives you dysphoria, vs what gives you euphoria. Which it sounds like you’ve already figured out quite a bit.
As far as a specific label goes, they’re meant to be descriptive. So the label that fits in a given situation is what works, and you shouldn’t have to pick one that is who you are. They aren’t meant to be prescriptive, deciding for you how you should be showing up. If that makes sense.
From what you describe, I would explore the nuances within the non binary spaces, and find some idea that fit you there, like maybe trans masc or something like that.
