Personally had the most success with Newpipe, but having tried pipepipe just now I'd probably go with that, seems like Tubular/Newpipe but better.
Free and Open Source Software

i use mainly freetube both on desktop and on android.
Since FreeTube is not available for Android, how do you use it on phone?
it's available on fdroid and github https://github.com/MarmadileManteater/FreeTubeAndroid
Oh it's availqble through Izzy, not native F-Droid, thank you.
you can also download the nightly dev apks if you have a github account from https://github.com/FreeTubeApp/FreeTube/actions?query=workflow%3ABuild
Piped unfortunately is not working.
If you're looking for an in-browser alternative I'd highly recommend you take a look at the LibRedirect extension for Firefox and Chromium. It'll automatically redirect any youtube URL to your preferred alternative between Invidious, Piped, PokeTube, CloudTube, Tubo, FreeTube, or Yattee.
If you're looking for an external app and like using a Linux terminal then ytfzf may be a good choice. I've briefly talked about it here. It will even allow you to search on Youtube (through invidious), Peertube, and Odysee if you so desire.
If looking for a phone app, I personally like NewPipe.
I don't use web browser on phone for content, although I use Free Browser for being pure open source withoit deoendancies, but I only use computer for websites.
I'm trying to figure out which app to you.
What about innertune? It's just YouTube music with no videos.
