“Kids” in quotations because sometimes “kids” shows aren’t really just for children, judging by their nuanced jokes.
Could be old, could be new.
I like a lot, two that stand out lately are Star Wars: Skeleton Crew, and Star Trek: Prodigy.
Going back a ways, Reboot and Beast Wars. (Reboot, upon relatively recent revisit earlier this year, has a few jokes that I certainly wouldn’t have gotten as a kid nor even as a teen.)
You?
Avatar both Aang and Korra, easily some of the best characters and world building for a kids show
Zoids
Teen titans
Lot of the nickelodeon shows around early 2000s SpongeBob, fairy odd parents, jimmy neutron, Danny phantom. They kinda were releasing bangers for awhile
Adventure time I watched as an adult and really enjoyed it
