In addition to the listed ships, I like gen for any character.
Prompts and likes (feel free to ignore prompts): Midgar! That whole gritty seedy steampunk atmosphere with occasional moments of just plain weirdness. Melancholy and loss. The past coming back to haunt you. All things to do with the original Avalanche characters (Barret, Tifa, Wedge, Biggs, Jessie). Trains, reactors, mako and materia. Human places being reclaimed by the Planet. Backstory moments for any character. Aeris experiencing the world outside of Midgar for the first time. Commonalities between Sephiroth and Aeris. Canon-divergence and alternate timelines (Tifa or Aeris in SOLDIER, anyone?) Tifa, Cloud, and Barret finding a home post-game. Yuffie getting a chance to show her more serious/heroic/competent side. Nanaki finding another of his species. Something from Jenova's point of view, especially if you can swing something sympathetic from Jenova's point of view. Spooky or supernatural elements, ghosts, magical realism.
Original game canon strongly preferred.
Terra/Celes is my fave and these prompts are going to be Terra-heavy, but I also love gen for any character (but especially Setzer, Edgar and Sabin), and anything to do with the espers and/or their world.
I couldn't ask for General Leo as a character tag, but I'd love something involving him.
Prompts and likes (feel free to ignore prompts):
For Terra: angst related to growing up as a lab experiment and being used as a weapon, figuring out who she is and how to live in the world, learning to deal with her own strength and abilities. Anger. Themes of betrayal and reconciliation, especially with regard to Terra/Celes. Xeno and magic-kink, again especially with regard to Terra/Celes. Seasonal and elemental metaphors. Magic not being entirely gone post-game, and showing up in unexpected ways.
For Leo or Celes: Growing up in Vector. Struggling to reconcile the Empire they believe in with the Empire they see. Loyalty, treachery, and the line between them. Second chances.
For any character: rebuilding after the end of the world. Surviving in the World of Ruin. Climbing Kefka's tower. Building and repairing airships. Magic and summoning. Folktales with some grains of truth to them. The espers being perceived as gods or Fair Folk, and not necessarily the nice kind. What is Gogo's deal, anyway?
DNWs: Modern mundane AUs. Terra/Kefka, or any non-con involving Terra.

In addition to the listed ships, I like gen for any character. I also wasn't able to list Auron/Rin or Belgemine/Yuna as ships, but I would love to see something for either of those.
Prompts and likes (feel free to ignore prompts): Bits and pieces of worldbuilding related to Spiran history, the Aeons, Al Bhed culture and beliefs, Zanarkand then and now. Atmospheric ruins. Yuna, Wakka and Lulu growing up together on Besaid. Yuna's choice to start out on the summoner' path, or one of the many moments she chose not to quit. The other summoners' motivations for starting the Pilgrimage. Stories. Moments of rest and recuperation along the Pilgrimage. Growing doubts about Yevon. Reconciling faith with truth. Sad stoic honorable dead people. Sad stoic honorable dangerous dead people. Vampiric or fiendish unsent. (I mean, you don't have to go there. I know it's ridiculous.) Rin as an alchemist. Rikku and Wakka finding common ground post-game.
DNWs: Auron/Rikku except as a one-sided crush, modern mundane AUs. I don't have any objection to past Auron/Jecht or Auron/Braska but for Auron I would prefer something set during the current game timeline or in Zanarkand rather than Braska's pilgrimage.
Original game canon (as in, no X-2) preferred, but not a dealbreaker

In addition to the listed ships, I also like gen for any character, and I'd be happy with any f/f relationship.
Prompts and likes (feel free to ignore prompts): Characters interacting with their machines – I love the way the vehicles themselves have a sort of life in this canon. Action scenes, violence, explosions, living on the edge of death. The Vuvalini being warriors and doing what's necessary for survival. One man, one bullet. Transforming the Citadel. Gardening, seeds, water, rejuvenation. Life in the Wasteland. Resilience and survival. Ruins, relics, and glimpses of the old world. Animals. Scenes from Furiosa's dark past. Furiosa and the wives growing to trust and respect each other, pre- or post-canon. Furiosa post-canon, trying to shake off Immortan Joe's legacy. Uncertainty and tension, searching for a redemption not yet found. Wasteland myths and belief systems. Crow feathers. Spooky or supernatural elements, ghosts, magical realism. Time and reality being kind of fuzzy in the Wasteland.
DNWs: modern mundane AUs. Non-con with Furiosa as the perpetrator or Cheedo as the victim. Extremely sexually-naive War Boys.
