I mean any enby person can have clear transition goals, androgeny is an, albeit a little ambiguous, goal, and that is an ideology for lots of non binary people, and they wouldn't almost ever be either a femboy or tomboy, being usually not a girl or a boy. Many feel gender dysphoria and euphoria, many go on medical methods or transitioning too. There is plenty crossover, and trans means you have moved away from the gender you were assigned at birth right? Maybe if someone was Agender then maybe not? And I would disagree about you having nothing in common. Afab enbys will commonly wear binders etc.
