Best approach for automatically tagging local music collection?

I don't use music streaming services much, and listen to music from my own local collection.

I don't use any local streaming servers like Plex or Navidrome, they wouldn't work for me because I use a dumbphone and play music off of my SD card.

I've manually built a bunch of mood based playlists so I can easily pull up a playlist with the music I want, but that's
obviously very tedious and inefficient.

I've been playing around with ML models to automatically add genre, mood, and other tags to my collection, the open models available today are insane.

The thing is I haven't been able to find any polished tools for doing this.

Most of what's available is either CLI or built for streaming servers.

Is there anything I missed?

Should I just setup a streaming server just for tagging the collection, or is there a better way?
