Same set-up here. Had tried many times over something like 15 years to get Kodi/XBMC working well. Nobody else could/would ever use it (the UI is so bad) and I bet I spent about 50% as much time screwing around to set it up and maintain it as I ever spent watching stuff on it.
Jellyfin, at first with the official client on Roku then on Infuse on AppleTV when x265 hardware decoding started becoming a requirement (my server is too weak to transcode) has been everything I wanted Kodi to be. Web interface is great, I share it with a couple friends over Tailscale. Wife and kids and visitors use Infuse, no problem, no complaints, no help needed. My use-to-fiddling ratio is probably literally 100x better than with Kodi. I have spent overall less total time messing with it than with Kodi, even including figuring out solutions for things like YouTube videos.
