Of course, creature types are kinda arbitrary in the first place...but these are more arbitrary than most.
Actually, there's at least one giant that's naturally medium, and dragon magazine gave us a Large humanoid, the quinametin (issue 317, page 65).

If your game doesn't use dragon magazine, that's even better. In that case, the various Shinomen nagas from Oriental Adventures never got updated, meaning there exist a few Large and even one Huge humanoid race.
