-G specifies the *local* subnet.  With ::/0, everything is local and
there is no remote, so nothing displays.  You probably wanted

   iftop -i wg0 -G fdf1::/64 # if there are other subnets like fdf1:1::/64
   iftop -i wg0 -G fdf1::16:3e75:72af/128 # if only your box is local

Again, the purpose of -G is to bisect the address space into "inside"
and "outside".

You might not have the latest, where the "pre" warning is removed.
