Hello brianvandsd,
Thank you for using the Apple Support Communities. Managing your storage space is always important. I understand you're seeing a significant amount of "System" storage in use on your Mac.
Which exact macOS version are you using under Apple menu () > About This Mac? As a starting point, updating to the latest release for your current macOS version is a good idea. Be sure to back up beforehand:
Back up your Mac with Time Machine
How to update the software on your Mac
Also, it sounds like you've looked into Time Machine local snapshots and a few other things. Have you reviewed the detailed reporting and suggestions here?

How to free up storage space on your Mac
Have you checked multiple locations to compare your disk usage? While you would generally see small differences depending on where you check, it may be worth checking Finder, Disk Utility, and About This Mac > Storage. If you notice any significant differences in your reporting, please include that information along with the results of the above!
Take care.
