All pairings are casual faves, I have very few squics and Notps. I will enjoy case stories or character studies just as much, if not more than something heavily romantic. That said, Parent-child relationships and mentor-mentee are a no go for me.
Fandoms I enjoy:
Any combination of Cap/Bucky/Darcy
Darcy as a character being awesome.
Aromantic Maria Hill (I’ve never read any stories featuring her being aromatic but it’s my personal headcannon and who knows maybe you’ve found something I haven’t.
Young Avengers comics
Matt as a character being awesome.
Young Justice (TV)
Teen Titans (the original TV show, not the terrible Go reboot)
Justice Society of America (Comics since as far as I know they’ve never gotten a TV show -- Geoff Johns run is my favorite.)
Any iteration of the Legion of Superheroes
Brainiac 5/Dream Girl
Crossovers for any of these are amazing.
Tropes I Enjoy:
basically anything with dragons….
Superhero AUs… for the fandoms that don’t already contain superheroes…
ABO, mating, collars
Tropes I Do Not Enjoy: ( These just aren't my favorite they're not true squics or hard stops just something to consider.)
Coffee shop AU
High school AU
Always a different gender AU
Things I am willing to podfic:
Anything on my approved lists
Hikaru No Go
Old Kingdom (Garth Nix)
Ex-heroes (Peter Clines)
Wearing the cape (Marion G. Harmon)
I also have a pretty long list of fics bookmarked to record here if you need any ideas.
