Cardcaptor Sakura is wonderful, I also recommend Sailor Moon. I’ve seen recommendations for Nichijou and I agree with that one, it’s primarily comedy without a ton as far as plot goes.

I saw this recently and it kind of blew my mind how good the animation is. Highly recommend.

I’ve personally been using a raspberry pi with a Bluetooth mouse and keyboard. I just run jellyfin in Firefox and navigate with the mouse - the keyboard rarely ever being necessary. I was able to increase the icon size so it’s acceptable on a tv and bookmark any streaming websites I use. It’s certainly not as clean as using something like an apple tv, but it’s serviceable and I don’t have to fiddle with plugins like when I tried Kodi. Honestly though, apple tv probably fulfills what you’re looking for like others have said.
