Most (all) of the creators I watch have patreon/buymeacoffee/merch/sponsored videos. I've heard from many of them that the amount of ad revenue they receive from YouTube is a rounding error compared to that. No reason every single creator on peertube cant put a link in the description to donate, sell merch, etc and its not conditional on tiptoeing around youtube's ai fuelled demonetization that constantly steals the little ad revenue they would have otherwise received
Anecdotally, about 25% of my circle have moved to various other services, so maybe not a huge disruption but they're definitely losing some customers to competitors at least
The *arr stack is what you're looking for + Jellyfin for streaming (Opensource, 100% free, and much better than Plex).
Prowlarr: manage your indexers
Radarr: find/automatically download movies
Sonarr: find/automatically download tv shows
Jellyfin: streaming your media
Look up trashguides for setting up all this stuff, very detailed guides. They are compatible with torrents and Usenet. I like using docker with portainer for easy management and if you use a VPN container you can selectively route these containers through the VPN so your other services that dont require the VPN dont need to route through it.
There's other frontends for fdroid available like neostore that handle it automatically
