And no, on the settings panel the sleep time is set at 10 minutes. I just lowered it to 5 minutes but it remains awake.

Is it because of Universal Control on the Mac mini? Is that what is preventing my iPad to sleep?
 
It depends on which iPad model you have. At least the newer M4 iPads, and possibly earlier models, feature an attention awareness mode. I'm not sure if this can be disabled somewhere, but as long as your eyes are on the device—for instance, if it's in a case right in front of you—the screen will remain active. If that's not the issue, you'll need to provide more details. See also this document from Apple.

My iPad Pro also stays awake when using with Universal Control, even when the cursor has been up on the Mac for awhile. I believe that is intentional behavior. I just manually sleep it by hitting the sleep button.

Edit: I’ve just disabled “Attention Aware Features” as shown in the Apple Support doc and will check to see if that changes this behavior.

Yeah, I just realised that’s the behaviour. What I do is, either block the iPad manually like you, or just go to the menu bar and disable the Keyboard + Trackpad sharing (Universal Control)

That’s not the issue since I leave the room, and the Face ID in my iPad cannot see me. But yes, that’s a great feature.
 
Disabling "Attention Aware Features" does nothing to alter this behavior. The iPad stays awake after the Universal Control connection has been established. This makes sense, because they don't want the connection to drop every time your screen goes to sleep (e.g., after 5 minutes, if that is the setting you are using), given that you cannot reawaken the iPad by trying to move the cursor back to that location (I'm assuming for this point that the pointing device is paired with your Mac, not your iPad). So sleeping/waking is done manually by the user once the Universal Control connection is established.
