Depending on your privacy needs you can use torbrowser for android. Mull browser (ffox-based) in f-droid is also a good pick - lightweight and comes with good add-ons.

If for youtube only, newpipe is a good choice indeed. Alternatively you can use any invidious public instance (yewtu.be is one) at api.invidious.io, or use farside.link/invidious for a random, working instance everytime.
