Projector with media server running Kodi with various plugins. Projector screen is unbreakable by kids or pets and projector itself is high enough to be outside a range of them.

Kodi is controlled by smartphones connected to home network so no need to store one physical remote controller.

Bonus: When you are outside home, you can still control remotely your projector/media server via VPN. Which is handy when you need control over what kids are watching.

Using like this over 6 years now, no complains and any reasons to change. Only disadvantage is that you need to spend one evening by configuration, but then it works as intended.
