I saw a post from someone wanting more trans memes and took that as a sign to post one of mine.
The Post-Self series by Madison Scott-Clary. This page has short descriptions of the books and links to where you can buy them: https://post-self.ink/
It is broadly about a future where people can upload there minds to a computer system, which makes them (barring some specific and rare circumstances) immortal and allows them to make copies of their uploaded selves. There are multiple non-binary protagonists, one of them also being aromantic and asexual. There are also polyamorous, bisexual and gay characters.
