Some folks mention about certain cartoons portraying parents (dad/mom) as dumb, but this can be very much said about many of the Cocomelon episodes (e.g. take the "are you lying? ha ha ha" as it being a joke to do something and then lie to your parent about it).

That being said, I would suggest checking out

• Old School Pokemon: many, many, many episodes and can be found fairly easily online
• Tina and Tony
• Kit and Kate
• PJ Masks Shorts
• Octonauts
• Wild Kratts
• The Fixies: while it originates from Russia, it is surprisingly very good and non-political; each episode is basically a lesson of how an item works with the little screws and bolts that transform into beings and fix items around the house.
• Robocar Poli: originating from Korea but is well dubbed
• Fairyteens: this one is for slightly older kids and can be a hit/miss
