Peertube

I'm new at both PeerTube and at Piped/NewPipe frontends. I've always wanted to support PeerTube but every time I browse instances I see very little content and it's especially barren for the type of stuff I like. Not really a tech guy, even though I'm learning some programming my background is that of a Literature teacher that likes gaming (especially indie gaming, but some AAA RPG/JRPG/narrative/strategy gaming is cool too) and video essays about anything that have at least a bit of humanities bend.

I've started using Piped to watch YT videos (I don't use NewPipe since I rarely use my phone, more of a desktop guy). I've heard you can watch both YT and PeerTube videos on NewPipe. Can you do the same at Piped? And if so, what would be the best way to find channels with the aforementioned characteristics?

Stuff in Spanish is fine too since that's my actual language but I assume there's not much stuff in Spanish in PeerTube and therefore even less quality content and even less quality content that caters to my specific likes. So I foresee it'll mostly be in English like in YouTube.
