Thanks for all the info. After some more research, I think what I might be looking at as one of the better options is KDE Plasma Bigscreen on an old CPU plugged in the HDMI since it's rumored that they are about to roll out a release fairly soon. This way I would have access to a browser (I guess) for streaming apps and also have YouTube with no ads. Other solutions all had some significant drawbacks it seems like or weren't fully implemented.
