For inhibiting handle-lid-switch, yes – logind always tries to suspend if
the lid is closed currently, not just when reacting to lid events.

Would that trigger a suspend once you unplug the machine and there is
a pending request which was inhibited?

I usually deal with this by running `systemd-inhibit
--what=handle-lid-switch ` to prevent the auto-suspend. If you want an
automatic method, here's some scripting around UPower or udev:
