For late-night visitors, it may be prudent to have a video doorbell. The “Ring” system (below) gives you video, plus 2-way audio with whoever’s there. This allows you to get some idea of who’s there and what they want, without any need to open the door first, or give the visitor information about your state of being armed.

If somebody comes to my door and announces its the police, my response would be to ask them to do their cop lights and siren for a second to demonstrate. Meanwhile having 911 on the line asking if they sent them.
