That you say She-ra handles it's storytelling much like Avatar has me intrigued more. I was interested when I saw it on Netflix, but now I'll have to check it out for sure. I also enjoy Steven Universe, so it sounds good.

I'm big on watching cartoons, so that's basically anything I'll recommend. xD But for some variety, I will start out by saying if you have ever enjoyed the stand-up comedy of Gabriel Iglesias, then check out his show Mr. Iglesias. It's basically a sit-com written with his humor. I believe he is one of the producers too? Don't quote me on that.

If you liked Avatar, then you should definitely take a look at The Dragon Prince! It's pretty much in the same family as the way you described She-ra and ATLA. You may recognize the voice actor for the main character. Which only adds to the comparison considering the humor is very like that of Avatar.

Am I allowed to recommend adult cartoons? Oh well! You've been warned! Aggretsuko is worth checking out, as it's not "adult" in the sense that a lot of people assume. It's writing is simply more mature because it deals with adulthood and situations in more down-to-earth realistic ways. It's also an anime, but has an English dub option, so no need to read sub-titles if you don't like them. And the artwork for all the anthropomorphic characters is adorable.

Apparently, I like cartoons with anthropomorphic characters, because I watched a few episodes of Tuca and Birtie—another adult one. It's weird, but I was intrigued and the best way to describe it is it's fun to watch. It's unique and different and all of the characters are energetic and delightful. I haven't gotten too far in, but I enjoyed what I've watched so far.
