Is Restoring an Intel-based T2 Mac using Apple Configurator the most comprehensive way to do a clean, factory-fresh re-install or would Disk Utility suffice?

Dear Community Member,

I've had some issues that appear to be resolved with a clean reinstall of my OS; however, since these were software-based and I'll need to take considerable time rebuilding everything from scratch either way, I'd prefer to wipe the slate as clean as possible.

E.g., there are some dangling volumes (mentioned by in Disk Utility from Recovery Mode) – 8 volumes exist but only 5 are visible. And it appears there's a Volume Group where the 'system' half got deleted–I know it's not supposed to be possible. What's done is done. Everything's backed up externally and in Time Machine.

So, what's the best course of action based on my intentions and the above info?

A. Use Disk Utility to erase an Intel-based Mac - Apple Support

B. Revive or restore an Intel-based Mac using Apple Configurator - Apple Support

C. Other?

(You can see the history of my problems below. I consider the basic diagnosis of corrupted system/data software–not hardware–as the best. But in case you want to see my homework and EtreCheck Report:
