If you're asking this question, pragmatically your Mac storage is probably too small for your current usage. Which means you'll be managing your storage more actively. If you have one of the 128 GB Mac configurations, there's almost no way not to be managing local storage contents.
The Other storage can well be your own stuff; what files don't fit into the other displayed categories.
There is a user tip that describes more about Other storage, what is installed, and how to investigate usage..
Add-on cleaner apps are problematic additions in general, and not something I'd usually recommend installing. Some of those cleaner tools have caused corruptions or other pernicious issues. macOS does pretty well keeping itself clean. Booting through Safe Mode can be a good cleanup, if you need that.
ps: This question is probably also better suited to the user forums too, as this doesn't seem to involve application development. If you are using Xcode, that can easily use 30 GB, plus whatever other tools and source code you're working with.
