Peertube channels appear as communities on Lemmy from my experience. Loops I don't think I've seen being federated to Lemmy before, so I imagine posts from instances using it get treated as pure microblogging, meaning barely anything gets fetched by Lemmy.

Also tangential idea so hidden as spoiler, but...

If a video platform has RSS feeds for their creators/channels, you could generate bots that send links to updates (new videos) as fediverse posts. Might be a good idea if you can't find who to follow within the network here.

I have yet to explore options on the "threadiverse" (Reddit & billboard-inspired forums), but on platforms such as Mastodon & Misskey (microblogging) and Friendica & Mbin (threadiverse / microblogging hybrids), you can generate new bots with @birb@rss-parrot.net.

And lastly on this point of RSS, aside from Youtube (for obvious reasons) and Peertube (since you can follow natively), sadly not many have RSS feeds natively, the major ones I know being Odysee, NicoNico and Newgrounds. Others you may be able to generate RSS bridges, but they could not work (those aren't official means after all), and RSS bots might not take these links (e.g. RSS Parrot avoiding certain types of links to avoid spam).
