easy way to manage audio metadata / file organization?

With Lidarr being not very functional due to the Unable to communicate with LidarrAPI - Lidarr API "Internal Server Error" 500 | Invalid response received from LidarrAPI | HTTP Request Timeout · Issue #5498 · Lidarr/Lidarr I have been thinking about getting rid of it altogether. I have only started using it recently and don't like it.

What I use Lidarr for:

• Find metadata for music
  • organize files in a consistent way base on metadata
  • obtain album art
  • create .nfo or other files
• Identify desired music and instruct download utility to get it (this is optional for me--- I can handle myself if needed)
• Do the above via a web interface which can be browsed nicely

I don't like about Lidarr:

• The not-really-open-source nature of it, e.g. this current problem, where you are reliant on their external server to run your own home server. I feel this might be a more pervasive issue in the Arrs but not sure of all the implications
• How unsupported it is to include work that the lidarr servers don't know about. There will never be a metadata database which includes all music. There is just too much music in the world!
• no audiobook/podcast support

I also have Jellyfin going for the actual serving/streaming of the music. Am not sure if it is able to fully manage the metadata and files?

Lots of options in the awesome-selfhosted list.

I could use a linux desktop app if it was better than a selfhosted server.

Thoughts?
