best spanish speaking country to study abroad as a black trans woman?

i’m a sociology major in the united states thinking of studying abroad somewhere in latin america for a semester or two to help improve my spanish and be immersed in a different culture for a while. i’m curious to know which countries (and cities) would be the most accepting as that’s one of my main concerns. i’ve heard buenos aires is pretty queer friendly along with montevideo but i’m just asking here to get some other opinions from people that actually live there. 🙂
