Welcome, cb2021, to Apple Support Communities!
One of the things I did that decreased my “Other” storage category the most was to turn off “Content Caching”: System Preferences -> Sharing -> Content Caching.
Another thing that can take a significant portion of the “Other” storage category are local Time Machine snapshots. Unfortunately, such are not easily “paired down” manually. (Yes. There are those that share how to decrease such—one at a time—but, in my experience, such has little discernible affect upon your Available storage.)
However, since Time Machine only keeps local snapshot “as space is available”, Time Machine will delete and combine such, as you need more storage, if given a chance—especially if you have an attached, external Time Machine Backup drive.
Are you trying to make storage available for a Big Sur upgrade?
