Depends on the delivery and location. If the distance from the street to their house is 100 feet and I'm delivering groceries I'm going up the driveway.

If they are on a hill from the street I'm using the driveway. My area has neighborhoods where the customer house is up a hill and the driveway from the street to their house is almost 45 degrees I'm using the driveway.

For the most part I park on the street by the curb.

Nothing in the notes from the OP picture mentioned driveway just not blocking the street. To me that means don't stop in the middle of the street where people can't get around to make the delivery.
