If you're interested I remember a list of various queer organizations.
There's https://lambdalegal.org/ which is roughly the LGBTQ+ equivalent of the ACLU, and they're currently involved in a number of cases trying to block trans health care bans.
Longer term there's also a network of state level legislative advocacy groups. I'm in California so know about https://www.eqca.org/ but some searching turned up the national umbrella group https://www.equalityfederation.org/federation-members which includes links to all the various state level groups.
There's also a network of LGBT centers which frequently offer support groups and health care and may offer other services. In LA there's https://lalgbtcenter.org/ and the various centers umbrella group has a directory of local centers at https://www.lgbtqcenters.org/LGBTCenters/
Then there's been other industry level groups, like there's a group I remembered as "noglstep" which apparently rebranded as "Out to Innovate" which is a professional society and global community of LGBTQ+ students and professionals in science, technology, engineering, and mathematics."
