I recently joined https://diode.zone . There's not much content. We definitely need more content creators on PeerTube. But there is the odd gem here and there.
If you use Newpipe (a YouTube 3rd party app for android) you can use it to interface with peer tube as well in a way that is somewhat* seamless.
Most of the people I follow are on YouTube, a few cross post to peer tube as well. Having one app that integrates both lets me use peertube where I can and YouTube the other 90% of the time
