“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.)

No specific episode. I can totally understand that somebody wouldn’t like it. First time I saw it was when my 5yo son was watching it, I found it horrible. Many years later I tried for myself and found it increasingly funny. As ever so often, I’d say the first few seasons are best.
