I can only speak from personal experience here, but I always use LVM on
servers and that has served me extremely well. I also always use XFS for
servers on which I store data.

LVM has been fundamental many times to be able to add more disks to my
server w/o long downtime, and even replacing disks with bigger ones
again w/o (or reduced) downtime.

I think this is a pretty important feature for a Server OS.

Copying TBs of data can take quite some time, and being forced to do
that while keeping the server offline because there is no LVM layer to
automatically move all the blocks really sucks.

Simo.
