I rather liked these two. Though I don't know where you draw the line at for too hetero :)

Continuum https://www.imdb.com/title/tt1954347/ Travelers https://www.imdb.com/title/tt5651844/

Why'd this get downvoted?? "Similar to x/y/z but more marginalized" is like my guiding principle when it comes to picking media lol. OP if you ever find any answers to your question, let me know! I liked Fringe too.

All that comes to mind is Timeless, but it's only marginally more queer than Fringe, and got cancelled on cliffhanger.

Orphan Black, maybe?
