LVM doesn't have any "advanced resizing" features per se.  LVM is simply 
a way of grouping a number of physical devices into a single logical 
device.  The "advanced resizing" is nothing more than whatever tools 
are available for the filesystem you choose to put on your LVM volume.  
So, if you choose an ext2/ext3 filesystem, you can use extresize (or 
whatever it's called) to grow or shrink you filesystem to occupy more/
less of the logical volume.  In order for you to be able to do this 
with XFS, you need a tool that can resize an XFS filesystem (I don't 
know whether one exists or not).  LVM does not really affect whether or 
not you can do this.
