The best way to handle transitioning from YouTube is to use GrayJay. Follow creators that you like and when any of them have a platform on a different service, subscribe to them there.
Besides YouTube, it supports any PeerTube instance, Patreon, Twitch, Nebula, Odysee, Rumble, Dailymotion, Ted Talks, etc.
I joined the fediverse when Reddit made their API changes.
For me, personally, I found Kbin/Mbin to be a sort of hybrid between Twitter and Reddit, and I wasn’t a fan of the layout. Lemmy felt a lot more like the Reddit-like experience I was looking for.
However, PieFed then came along and it feels like Reddit, but has features that cater to the Fediverse much better than Lemmy does (such as being able to combine communities into feeds, crosspost handling,), as well as other features that are great (polls, spoiler blur for image posts, etc.).
I don’t remember the exact search, but it had something to do with Star Citizen. A link to a post from that Lemmy.world community was fairly high on a DuckDuckGo search result.
Along with a few other users, I’ve posted some useful links and info in the community over there. It looks like that work is starting to pay off.
I find it useful to sign up for multiple accounts and then segregate those into browsing/posting habits for different categories. One for gaming (or other relaxed communities), one for science & tech, one for politics that I only occasionally dip into, one that’s a voting only account, etc.
At the very least, you can take a break from communities that can easily be more toxic, whenever you want. If downvotes bother you, I would also suggest signing up with a fediverse instance that disables downvotes.
I’ve actually started to see some results from Lemmy.world in DuckDuckGo search results.
I don’t think the official Reddit app has ever supported this, unless it’s a new feature?
Only 3rd party apps supported this, but a lot of those have been killed off. You might still be able to access this feature through old.Reddit:

I’m not sure if you meant “multi-communities”.
In the fediverse, PieFed is a useful one where you can combine different communities into “feeds”.
For instance, there are a bunch of different “technology” communities, but all of their posts are combined into this feed: https://piefed.social/f/tech
In android, if you go to the website, then click on the 3 dots -> Add to Homescreen -> Install
Then you’ll be able to use PieFed and browse communities in the way (i think) you’re asking.
Otherwise this is also possible with the Android app “Eternity” which let’s you create your own “Multicommunity”. The advantage to the PieFed one is that someone else has already scoured the fediverse for you and combined them.
Next up, we’ll have to change terminology for “parents” and “children” once they find out how we use those terms with memory management.
