So it depends what you want to do, if it's just playback(as in you get your media via another device) any device will do just fine like a Pi4 with an external HDD(especially with them dropping in price after Pi5 announcement). However this will limit your expansion so the question becomes how much storage you think you will need. As the TV can nativley handle all those formats you don't need to do any transcoding, however personally I would say get something with a little more buffer room for if you ever do wanna play from a device that can't nativley display those things, or for if you ever want to expand your storage.
