Sleeping the iMac isn’t necessary, just let it switch off the display on timer. Disable Sleep in Energy Preferences too, it’s unnecessary on later Macs, all pain, no gain. Shut for long absences i.e. > 2 hours. To disable, check “Prevent…” in Energy Preferences and uncheck everything else. You can leave the display off time as is, unrelated to Sleep.
