I only had issues with the latest tag when dealing with the community apps. Some of them would randomly break and I’d have to roll back. Once I manually configured the docker settings using normal file mounts things were plenty stable. I think the issues were with the k8s community charts not with the underlying software. And that was fixed by just configuring it manually like however the dockerhub docs suggest.
I would still have the occasional issue where a container would freeze and a force stop wouldn’t work, and spinning up a new one wouldn’t work because the ports were still used. But I traced that back to a bad ssd with write timeouts. I still think truenas’s k8s wrapper is buggy. Even if a container crashes hard, I shouldn’t have to reboot the system to fix it. I switched to unraid and have been blissfully happy since.
You can add overseer for jellyfin, emby, plex based on your preferance, and it connects to sonarr and radarr. Overseer is good for finding recommendations and adding them to your queue. The reason I’m talking about it is you can specify your language and your region for recommendations to help you find good content. As for downloading it, in prowlarr when you search for an indexer to add (public or private) you can filter based on language. Unfortunately when I did it just now for de-DE the 30 or so indexers that popped up are all private. I don’t know their quality, but that is at least a list to start with investigating how to join.
I do know the BIG english ones have a lot of content including content in other languages or dubbed and marked as multi-language or multi-subs. My recommendation is to google around for big public indexers reguardless of language, add them and search for the content you want while also working to get added to the local private ones.
