I used to run Plex on a 3b+ and it couldn’t handle transcoding at a reasonable quality - jellyfin would presumably be fine as long as whatever device you are streaming from can handle your native file format (my library was x265, so I had to use the Plex desktop app because Firefox doesn’t support x265 and required transcoding)
More than. I was running adguard “hole” on a 2B over ethernet, a 3B is going to have computing power to spare for additional tasks if you so choose
I ran PiHole for a year on a Pi Zero W, before I eventually had to move my DNS server outside the network due to other requirements
And what about installing this plus Jellyfin or something similar?

Probably not. 3Bs are pretty old.
The 3b+ can stream 3 local direct streams without issues so long as there’s no container translations i.e. no HVEC or x265.
Plenty reasonable with a 1080p only Radarr/Sonarr setup.
(This was my experience with Plex on a 3b+ for many years at least, I’d be surprised if Jellyfin were any different.)
