Best solution for these concerns in my opinion is
- TV for presentation in companies (often without smart apps)
- PiHole for blocking the most adds
- SHIELD for the apps, like YouTube without adds, stream apps, emulators, etc
Works like a charm for me, I did not see adds for month, maybe years. With the shield, I use SmartTube because I can login and don't have any adds. None. I also use an app for streaming (moonlight or something like that) to play my PC games on my tv with controller.
