What did you do that led you to that conclusion?
I think
echo mem > /sys/power/state
is an init system independent way of suspending. The resume will be
recorded in syslog. For "systemctl suspend" the journal also writes to
syslog on Debian..

As I said, I would approach the problem starting with a minimal system
and working up. It has the advantage of leaving your system untouched
for later testing. If there is something fundamentally wrong with
suspend and resume it is unlikely that what is done with Xfce has
anything to offer by way of a solution.
