Two things immediately come to mind reading your thread.
The first thing that generally comes to mind is that every student needs to have at least one solid safety. UT Austin is an excellent university. Being auto-admit there, assuming that you can get your desired major, gives you a great university to have as a safety. Assuming that you are in-state it is likely to be relatively affordable. With a safety that is this good, it is entirely reasonable for any other applications to be to reaches, or even just one reach (and yes this is what I did also years ago, although not the same in-state/in-province safety).
The other thing that comes to mind is that your grades, course rigor, references, and fit are all likely to be more important than your SAT score. Your grades are excellent. You seem to write well, and have a good explanation for why Georgetown is a good fit for you. Being fluent in five languages (including English) should also help you given your intended major.
Your SAT is closer to their median than to their 25th percentile, and is quite good and a solid score.
And I think that @momofboiler1 is exactly correct that the rest of your application (other than test score) looks very solid.
I would go ahead and apply EA to both UT Austin and Georgetown, and see how it comes out.
