Ideally, a short story between 1,000 to 5,000+ words I would prefer.
Flash is actually 100-1000. I kind of like that length for some themes and ideas. Forces me to rein things in and focus more tightly, but can still tell a full story, vs. a micro where you're really just giving the bare bones.
Genre-wise, I am generally open to anything. Some of the best comps I have been in are ones where there is a broad theme that can cut across genres rather than a specific genre. So there was a "punk" comp I was in one time that was basically open to anything themed around "punk" genres like cyberpunk, steampunk, dieselpunk, and so on. And, of course, just punk culture and music. I think for a comp that works better as a focus than genre. Even a "space" themed comp could work that way. Even if it leaned heavily to SF, you could also have stories about modern space exploration (e.g. something involving astronauts on the ISS or its Chinese counterpart), astronomy, and such.
