Focus mode - block contacts but receive calls/sms from unknown due to deliveries etc

Time sensitive doesn't work here because how would whatever decides something is time sensitive know that a random call is the delivery driver asking for directions? Or that the SMS is from someone saying the door buzzer didn't work?

If I'm expecting a delivery (which let's be honest, most of us are given work from home) I can't use focus mode because of this, so I still get notifications from friends and fam all day.

Is there an option or setting I'm missing somewhere? Thanks!
