There is Nuclear. Note that sometimes songs can’t be downloaded, though.

Hmm certainly not nice seeing it shilling FB. There’s also FreeTube (desktop) and NewPipe (mobile), though I didn’t have nice experience with FreeTube—some basic features like creating a new queue are not there.

Electron apps is essentially running web apps wrapped as a desktop version.

worse even: it includes different copies of chromium in each app

i’m on mobile and see the svg just fine
