Everybody else said bonding fics already, but that's still my main answer. I especially like seeing bonding moments between sisters who usually contrast each other. Lynn in particular, since the show itself doesn't really seem to show her one-on-one relationships with anyone besides Lucy very much.

Other than that, I like fics that give the characters some more character development than the show would really be able to. Showing that there's more to Luna than music, more to Lynn than sports, more to Lori than her phone and Bobby, etc.

I also have have a fondness for "One of the Boys" style AUs. That one in particular may have been done to death, but I like other ideas with similar concept. Age swaps, personality swaps,"X character swaps places with X sister", so on and so forth.
