From poking around, it seems like GSM (Gender and Sexual Minorities) is the general successor to LGBTQ and all assorted acronyms. Obviously not as popular but it at least has everyone baked into it and doesn’t have any charged language, given the ongoing debate over whether queer has been reclaimed as a word or remains a slur.
Though, immediately after discovering it I did see people adding an R to make it GRSM (Gender, Romantic, and Sexual Minorities), which in theory covers every possible member of the LGBTQ+ family.
