In case you hadn't noticed, root doesn't have $HOME on /home
(unless you've adopted the Easthope scheme). I don't know what
the sudo-exclusive people do. For decrypting /home remotely,
I set up a special user that only performs that task (in order
to avoid logging in as myself or root).

AFAIK, blkid is a command that lists attributes or messes up your
system. Hence this, in bold, from its man page:
It is recommended to use lsblk(8) command to get information about
block devices, or lsblk --fs to get an overview of filesystems, or
findmnt(8) to search in already mounted filesystems.
So it's the attributes that should concern you, like LABELs and UUIDs.
In your narrative above, you'll probably lose swap each time you
reinstall, because you've set a swap in the partitioner. I always
avoid that. Any 21st century PC should be able to install with
needing to swap.
Cheers,
David.
