A couple of things.
1) please do not use "transgendered" or "cisgendered". The correct terms are "transgender" and "cisgender" because these are things that people are, not things that happened to them.
2) I've never seen the term "non-cisgender" used by people in the community, although I suppose it's not the worst thing. I'd avoid it, though, and say "transgender or non-binary individuals." Also note that "nb" as shorthand for "non-binary" should be avoided, because that term is already in use in the Black community to mean "non-Black."
3) "person assigned X at birth" is generally considered acceptable.
4) I'd steer clear of using someone's anatomy as a descriptor. It's really invasive and is nobody's business. I need to run to a meeting but I will try to come up with an alternative for you.
Thank you for asking these questions! I really appreciate that you're trying to get things correct and want to be inclusive in your language.
