Was actually unaware of SmartTube. Looks like it may cover that part for me :). I had also never heard of LineageOS, I'll take a look there too. I have a Pi4 laying about I was going to use.
As for FireTV I may just end up going that rout, I was just curious what the options looked like. Thank you for taking the time to enlighten me :).
Thank you for the tips! This seems like it may be a good option.
