 If you’re a fan of suspend-then-hibernate, like me (ideal for laptops if you ask me), you should edit the file /etc/systemd/sleep.conf, remove the # in front of HibernateDelaySec= and add the number of seconds. I have 7200 seconds (2 hours). You also need to configure it in your Desktop Environment after that. Gnome has no setting for that, but KDE Plasma (Settings-Power Managment) does.
