Lots of great suggestions so far. If you settle on aero, two more safeties that are very strong in aero are Iowa State and U Houston, so take a look and compare those to the others in your list.
Iowa state is rolling admission and their own app is easy and opens 7/1 (this Friday!). You could have an acceptance in hand before you start senior year. OOS COA is around $40k for 2022/2023, and you will get merit there too.
