I commented on here before about this. I'm certainly not perfect, but what I've done is basically YouTube is something the kid doesn't watch on their own. They can watch documentaries with me or whatever (occasionally some video game stuff), but almost all YouTube kids is awful. There are a lot of really good kids shows out there across different streaming services with actual plots and character development that make them think without frying their brains. For a kid in the 8-14 year range: Avatar the Last Airbender, Gravity Falls, Owl House, Dragon Prince...etc are prob fine depending on the kid (dragon Prince is a bit darker). As a parent you need to make sure they're not watching content you object to though. I'll also find some episodes of something like Star Trek that is interesting with some moral dilemmas and just talk it out with them. TV is fine in moderation. Make sure you keep reading to them as well.
