Linux as well.  BSD is not something I have much experience with and until
recently, none with ZFS.  Even the little experience I have with BSD was
well over a decade ago, maybe two decades ago.  I barely remember it really.

Hummm...I don't know Dale, I don't know... ZFS is a file system.
LVM is an abstraction on top (or underneath?) of a file system.
My understanding of LVM is that it frees you from hard decisions
on partition sizes, not that it replaces ZFS or ext3/4/5.

You may or may not know this but TrueNAS is available as a
Linux version:

https://www.truenas.com/blog/first-release-of-truenas-on-linux/

I don't recommend it. It's new. Let someone else figure it out. However
it might be more to your liking, and because it's Linux you'd be more
comfortable messing it up. ;0-

WRT you I recommend that you try living in NGL for a while. Possibly
you are just a bit too indoctrinated in the religion of building packages
30-50 times a year believing (without hard data) that it provides value.
Instead you might just consider relaxing and letting the system
take care of itself. In the last year I've only updated my TrueNAS box
twice that I can remember.

On the other hand if system tweaking is what brings you joy then
Que Sera Sera .....

Good luck,
Mark
