I have a similar setup. I’m fortunate enough to have a garage though. So I can easily go around if I need to.
You could also try propping your screen door open when waiting for a food delivery. I would do this with mine but then it blocks the doorbell. I got a little mini folding wooden table I can leave out, and put a sign indicating to leave the food there. (I also don’t like my food bags touching the ground because I’m a germaphobe. Though I’m sure their filthy DoorDash cars are dirtier than my door mat.)
