Not certain what age level you're looking for, but here are some I don't see on your list. A few of these have been mentioned by others, and I second their opinion.
Chowder Kick Buttowski Over the Garden Wall (some spookiness) Thundercats Home Movies (occasional light swearing) The Amazing World of Gumball Regular Show (some light adult themes) Inspector Gadget G.I. Joe Super Friends (1970s-80s)
