Thank you for the reply. :-)
Today, I was preparing a disk and (re-)discovered that geli(8) can do
data integrity verification:
init Initialize providers which need to be encrypted.
...
-a aalgo Enable data integrity verification
(authentication) using the given
algorithm.
So (?):
* geli(8) for data integrity verification.
* gmirror(8) for data integrity repair via data redundancy.
* gstripe(8) for capacity (RAID10).
newfs(8):
* Defaults to UFS2. Are there any good reasons for choosing UFS1 today?
* I see three related options -- journaling (-J), soft updates (-U), and
soft updates journaling (-j).
* Is -j alone equal to -J and -U together?
* It appears -j is incompatible with mount(8) live snapshots (?).
* Is -J compatible with mount(8) live snapshots?
* Is -U compatible with mount(8) live snapshots?
* Other feature interactions I should consider?
I own a stack of Lucas books, notably the following:

Are there other resources I should read?
Comments or suggestions?
