You can create as many logical volumes as you like with minimal sizes and easily extend them when needed. This way you don't waste space in overprovisioning.LVM greatly simplifies the partitioning part of the chore. But you still need to do the content management part[*] before shrinking / after enlarging an LV, don't you? [*] backup, umount/swapoff, resize2fs/mkswap, mount/swapon, (unlikely but possibly: restore)
Most common filesystems such as ext2/3/4, xfs or btrfs can be extended online while mounted. Extend the logical volume, then resize the filesystem, that's it. A swap cannot be extended while in use [*], but you can create and add a new swap instead. If you install with minimal logical volume sizes and leave plenty of free space in the volume group for future logical volume growth, you do not need to reduce existing logical volumes to gain free space.
[*] Actually it cannot be resized even when not in use, but it can be recreated with the same UUID and/or label, which provides about the same result as offline resizing would.
