In your own space, Talk about your favorite trope, cliché, kink, motif, or theme.

This is difficult because I don't tend to think in terms of tropes or themes, but having gone through TV Tropes list of fanfic tropes, I've picked a few.

Fix it - everybody lives My favourite characters always die, usually half way through. Qui-Gon, Norrington, Loki (even canon couldn't keep him down but I didn't know that at the time), Hux, Jin Guangyao... pretty much if I love any character it's a death warrant. Therefore I have to write fix it fic where they either don't die or they come back.
Hurt/Comfort where the hurt is minimal and got out of the way quickly (maybe even explained in flashback if necessary) and the comfort can be either physical or psychological. Ie, unlike in canon, people are actually nice to my blorbo for the first time ever. This often leads to
Villain redemption. I don't want the villain to have to grovel and repent on their knees and spend the rest of their lives in sackcloth, because so many of the villains I love are villains because they were treated like shit in their lives. I want them to get some therapy in which they are comforted and told that they too are valuable people who can make a real contribution to society, and then shown - maybe by someone who is willing to be their external conscience - how to put their considerable talents to work to improve society rather than destroy it.
There doesn't seem to be a name for this trope, but most of my fics are examples of this: Two people with extremely opposing views are put into a situation where they are forced to talk to each other and explain their points of view. I don't really mind if they can't reconcile in the end, but I just want people to be allowed to explain themselves.
