TL;DR let's go the s2idle way as that is the only one which may work. But for
me it resumes immediately again (similar to the "suspend" Bugs below).
Also I had to do 'echo freeze >/sys/power/state' for s2idle as systemctl has
no such option (nor there is any GUI option for s3idle AFAIK).

The problem is "suspend" depends on computer BIOS, sometimes it does not work
and due to the BIOS it is difficult/impossible to debug:
Kernel fails to suspend due to rmi_smbus
https://bugzilla.redhat.com/show_bug.cgi?id=1480602
Cannot successfully suspend, machine starts again after a few seconds
https://bugzilla.redhat.com/show_bug.cgi?id=1781566
Bugs in "suspend" are also mentioned in the first article about "S3":

I agree hibernation also sometimes does not work for me (in 20% cases it just
suddenly reboots during resuming); X1 Carbon 6th gen (Red Hat one).
Having both suspend & resume was useful one had a chance at least one of them
works sometimes. If the 'out of the box' installations will no longer offer
the hibernation option it means less compatibility with hardware.
