I assume being Apple that it’s not possible to sideload apps not supported on the app store? In particular I’d like to use some kind of a SmartTube or other youtube app that is ad free
You can use sideloadly but IIRC you need a Mac for it to work. My YouTube workflow is a YouTube-dl wrapper that pipes into jellyfin for the small handful of things I still watch from YT, so I’m less familiar with live YouTube interfaces to know which ones are out there.

That is correct.
But which do you want? Privacy or convenience? No one makes a streaming device that does both.
