One of the newer one I liked:

Centaurworld

My Adventures with Superman

The classical 90s ones and early 2000s on top of the others already mentioned. Not in order: Animaniacs, Batman the animated series, Rugrats, Hey arnold, Dexters laboratory, Powerpuff girls, Justice league, Teen Titans, The Angry Beavers, Ben Ten, Kim Possible
For cultural reference: Ren and Stimpy, Courage, the cowardly dog, Cow and Chicken, Jhonny Bravo
The Disney series: like Duck Tales. Tailspin, Gummy bears,

These are top of my head. Yes I do love cartoons. And anime too.
