That main points about XFS are covered in the thread I invited you to read.  
Twice. In the last paragraph of this post for example:  
https://trisquel.info/forum/partition-table-suggested-installing-three-gnulinux-systems#comment-69798

You could use an XFS filesystem for /home. It is said to be be faster for  
large files such as user files. However it cannot be shrunk.

The actual GNU/Linux distribution does not matter for the choice of a  
filesystem type.
