NFS will force you to use Thin. The other options will be greyed out. Because vSphere does not "own" the storage with the standard VMFS partitions it is up to the underlying file system to write the blocks.
Here's a link to my NFS on vSphere Deep Dive series.
I wouldn't bother with independent disks - just leave it default. This has more to do with allowing snapshots than anything performance related.
Most of your performance numbers are going to come from the underlying disk configuration / raid group(s) / network bandwidth / power of the NFS controller (in this case Windows).
