Craig of the Creek was also pretty good, though I don't think it has a wider arc (I am not entirely certain though.)
I'd also recommend getting your hands on the cartoons you enjoyed as a kid. Odds are good your kids will like them for the same reasons you did, although you may find that they don't all hold up for you.
I grew up with WB Loony Tunes (and Tex Avery and Superchicken and Wacky Racers and...), and that style of animation looks positively ancient in comparison to the modern animation style - whatever you call it - rendered as sort-of-3D. For example, Paw Patrol.
This actually worries me because I want my kid (currently 5yo) to have the benefit of the utter anarchy of Bugs Bunny and Daffy Duck and Roadrunner.
Some of them, Adventure time being a great example, can appeal to very young kids but they'll find new meaning in those episodes as they get older.
I think shows like Infinity Train, Avatar the Last Airbender/Legend of Korra, Steven Universe, and Samurai Jack will be better after a kid is old enough that Cocomelon wouldn't hold any appeal, but even at that age Sarah & Duck, Hilda, MLP, Craig of the Creek, etc could still be good. Just about anything that holds their attention and isn't Cocomelon is a huge win. If you'll enjoy it, all the better.
Old episodes of Blues Clues are also great for little kids.
It's a bit annoying really because there isn't anything else like it at all. I would say the closest things are Pixar films which manage to appeal to adults and children. I'm not aware of any TV like that though. Apart from Bluey we're stuck with trash like Paw Patrol, Bing, Blippi, etc.
There are a small number that are not extremely annoying, but you still wouldn't actually want to watch them: Gabby's Dollhouse, Puffin Island, maybe Hey Duggee.
