I dont even have root. You download the apk for the recommended version of YouTube, which the revanced manager app tells you, select it - it auto picks all the patches - hit apply, wait - then hit install. Takes maybe 2 minutes to install. Then you're done. Never once had any difficulty beyond that. One time I used a different youtube version than what was recommended, worked fine just didn't have all the patches.
I dunno why you were trying to sideload it. That's not necessary. You can do all this in, I'll be generous and say 15-20 minutes. I've done it a few times now and done it for others too, so it usually only takes me 5 to 10. Depends on how fast their phone is to patch the apk.
Throw in another minute to fully disable the official YouTube app and route all YouTube links to open with revanced and you're set.
I love socially interacting with my co-workers. I can just as easily do that over teams. Better honestly, as if I'm focused heavily on a task, I can take a moment to stop at a convenient spot before checking my messages. As opposed to having people literally walk up to me or just start talking to me while I'm busy doing something. The face to face conversation was nice, but the pros far outweigh the cons in my opinion.
I personally will never go back. I have adhd and being able to stay home and thusly have 0 commute time has been an absolute wonder for my well-being.
