Maybe "rear" is an appropriate solution for you?

I would include LVM and mdadm info as well, since I use those
features. I encourage you to look at what long-lived tools, such as
clonezilla, write into their archive directories. It's impressive.
If you zero out all free space on all of your HDD partitions (dd
bs=1M if=/dev/zero of=/path/deleteme; rm /path/deleteme) or use
'fstrim' for SSD's, you could use dd to image with fast & light
compression (lzop or my current favorite, pzstd) and get maximum
benefit of a bit-by-bit archival copy.

Short of backing up entire disks using dd, I'd like to collect all
required information to make sure I can restore partitions, disk
information, UUIDs and anything else required in the event of losing a
disk.
So far I am collecting information from:
- fdisk -l
- blkid
- lsblk
- grub2-efi.cfg
- grub
- fstab
Hoping that this would supply me with /all/ information to restore a
system - with the exception of installed operating system, apps and
data.
I would appreciate any and all thoughts on the above!

Thank you, that tool is new to me but looks very interesting!

Yes, indeed. Up to now, I have very good experience with that. Setup new
server. Create "rear" backup on USB, nfs-share or more secure via
sshfs. Destroy Raid, Create new Raid. boot from rescure image. type
"rear recover". DONE. All that in less than 10 minutes.
