Lots of good answers for higher education already, so here's my pitch for you to consider a shorter time period with less debt or cost in trade school.

Technical school and/or trades work with lots of volunteering. Plumbing, electrician, etc. that's all good honest work and it can really transform people's lives if you come around to fix their shit for them in their homes. Plus, if you make it to journeyman you can take on apprentices and provide employment and training to oppressed people. You can join a union or start a coop with a few other like minded trades workers. Most trades I've been around are pretty chill about GNC people or female presenting people, but I've never been on the receiving end of harassment for it either. It kind of depends on trade, from what I hear.

It doesn't have to be a trade, something like EMS or medical sonography or more technical education in utility companies are all good as well.
