I was looking into setting a docker container of Picard, and see what I could do with it. However, I was looking for the most automated solution I could find; and happened to land on Beets.
Though I may still try out Picard as a supplementary option.

Picard is the way to go if you want to get the highest quality tagging with exact release matching. Most would probably not care too much about this, however when I know my files were ripped from a Japanese release, I want the tags to reflect this. Picard allows me to find the right match before any tags are written. This is especially helpful when you have two or more different versions of the same album, e.g. one CD rip and one vinyl rip, or two CD releases with different set of bonus tracks. My directory structure and tagging rules allow me to manage this consistently with no manual workarounds.
