[Fast Startup doesn't affect 'sleep'. See more below.]

  With "On sleep", you probably mean on Shutdown, because when Fast
Startup is enabled, it only affects, what happens during shutdown
(does a hibernate  of the OS, not the user session, etc.) and what
happens during boot/power-up (resumes from the hibernated system copy),
it does not affect what happens during sleep.

  Also the "That's in case power is lost during sleep" is misleading,
because that's not the/a reason for Fast Startup, I even doubt that Fast
Startup will use the hibernated system copy when rebooting/powering-on
after a power loss, because  the system might have been changed since
the time of the *previous* shutdown, so the hibernated system copy might
be stale/invalid.
