I think allmost all; except Mandarin ducks and other special-looking ducks. In my experience those are less tame/cuddly; and male-female pairing ducks are often more "loners" from the group.
So Indian runners, pekin's, muscovy's, cayuga's, every group-duck can be an lovely asset. Where I live it is illegal to clip their wings; if that's the same over there I would go for non-flying duck breeds; or if you find it a hassle to clip them.
