I agree with you about Auburn. We are in state Georgia as well. My oldest was wait listed at Georgia Tech and was a wireless engineering major at Auburn. His academic profile was not quite as strong as the OP. He was awarded the presidential scholarship as well as some smaller departmental scholarships (they stack), and was in the honors college. He had no problem landing internships and co ops - and yes he was working with students from several other schools including Georgia Tech. His friends in aero and a few of the EEs he knows landed positions at Lockheed, Boeing and at NASA in Huntsville. At least for my kid, I feel that being the big fish in the small pond worked to his advantage.
I will also add that everyone we know that did Georgia Tech distance math and did well (ie an A or B) was ultimately accepted to Georgia Tech. Our private school didn’t offer it,but I have a lot of friends with kids in some of the Uber competitive public schools in both Cobb and Forsyth whose kids did the distance math and were accepted. I have heard claims that the Tech acceptance rate for students in the program is upwards of 80 percent - but you may have more insight into that than I do.
