"Before Stonewall" is an excellent documentary to watch. Paris is Burning also doesn't hurt to watch but it's notable to keep in mind that it was made outside of the queer community for the purpose of sensationalizing and exploiting us even though it is still grounded in reality.
I’m a fan of these resources in particular, as a bit of a gender and intersectionality intro: Candace West and Zimmerman, “Doing Gender” Kimberle Crenshaw, “Mapping the Margins” Jules Gill-Peterson “A Short History of Transmisogyny” Paris is Burning Cathey Cohen “Punks, bulldaggers, and welfare queens”
