If getting into LVM, I highly recommend going the extra mile and going ZFS. You have as many mounts as you want with pretty much any parameters you could want, encryption, case insensitive, compression, you name it. And if you end up really needing a partition, vdevs gives you that, and they only take the space that’s actually used. So if you make a vdev for a VM and the VM uses discard/fstrim, it releases all that space back to the host transparently.
I’ve had so many weird problems with LVM especially mirrors and raid. Even snapshots are kinda bleh. I’d take btrfs subvolumes over LVM. It’s barely any more flexible than a regular partition table…
