I don't think there is any reason to "worry" about the abilities of a 20ga shotgun.

If you are worried about the roadway being a background, there is an easy fix to that.... simply face another direction. Nothing says you have to stand facing the door that someone is trying to kick in.

Now is the time to invest in a little better door and perhaps add a storm door or other security type pre-door. If someone wants in they will get in but the idea is to make it difficult as possible. I also suggest the large striker plates that spread the screw holes out off-set.

I will say good-job at being armed and ready prior to the fellow getting inside. Now get to work on making entry a little harder.
