Mac Pilot, a customization and utility app from Koingo Software is currently $3.00 on BundleHunt. There are similar apps like Onyx and Tinker Tool out there that are free, but for the price I thought I'd take a look.

System Profile
In addition there is a section for getting more information and doing some optimization but it requires disabling System Integrity Protection and I did not explore that.
The final potentially helpful tool is one that strips out the files from binaries for either Intel or ARM processors if you are running low in disk space and want to eliminate things you don't need. I'd make damn sure I had a good backup before using that.
