Your best bet, I think, is any village that has a team of genin. There's a list of characters and which village they're in on the first post of the first page of the IC. Konoha also seems particularly active.

Depends on what Genin wants to learn kenjutsu/wind/lightning techniques. Totally being a high level. Been a genin too many times in my lifetime. Also wanting to murder the Hokage would put a dampen on being in Konoha unless I'm some double agent for the Republic that's been in Konoha for like...years upon years.
