Proper way to reformat and reinstall on an Intel MacBook Pro w/ T2 chip

I have been encountering increasingly frequent issues with my 2019 MacBook Pro. In particular, the deleted_helper process constantly runs at 100% CPU, seemingly random crashes, and most recently, application lockups when doing things which require reading from or saving to the local disk.

All of this seems to be related to filesystem issues which Disk Utility and fsck are unable to fix. Specifically, "fsroot tree is invalid" with "error: ban: invalid key order: index X is greater than index Y". This started with a single key order error, and has progressed to two, and now three. These issues specifically show up on the "Macintosh HD - Data" volume (the "Macintosh HD" system volume doesn't show any errors in Disk Utility).

My understanding from reading past posts on this forum is that one troubleshooting step worth trying at this point is to wipe the drive and reinstall, and that this needs to include erasing the entire APFS Volume Group (not just "Macintosh HD - Data").

My question is: What is the proper way to do this in a way that will actually erase the whole Volume Group and allow me to reinstall from the Recovery partition?

Apple Support docs say that when working on Intel Macs with a T2 chip, one should use Erase Assistant instead of erasing the volume group using Disk Utility. However, my understanding is that Erase Assistant doesn't actually erase the volume group, it just operates on the Data volume and allows it to be overwritten.

Will booting into Recovery and using Disk Utility to erase the "Macintosh HD" APFS Volume Group actually cause me problems when I try to reinstall from recovery, or is it just less efficient than using Erase Assistant?

I'm currently running Sequoia 15.6.

Thanks!
