How to set sleep begins at xxx in Catalina?

How is a sleep setting made in Catalina? I don't see it. In Sys Pref I see turn display off after xxx or don't sleep when display is off. I always understood the display on/off and sleep on/off were not related. The display could be off and the computer on and put to sleep later.

I also see an option to require password after xxx time asleep or screen saver starts.

And another option to log out after xxx minutes of inactivity.

Pretty confusing unless screen saver on = sleep begins.

What sets sleep begin interval?
