If your goal is to be in academics, you should still keep region in mind. Connections are important to getting hired.
Random example (I'll choose Mayo since I know least about them):
If you go to Mayo and stay at Mayo for fellowship, assuming you're somewhat normal and maintain an interest in academics, you will most likely have priority at Mayo.
You will also have priority at other institutions whose faculty know Mayo faculty well. This is likely to be in that region. For instance, I don't know anyone on faculty at my institution who works closely with anyone at Mayo. That doesn't speak badly about either institution, that's just the way it is.
An exception is that if you publish more than a little with someone who's truly expert in a particular field, then you'll have a wider area of pull. These kinds of mentors are not common.
If you were to go to Mayo and then go elsewhere for fellowship, you've widened your connection pool.
I know Michigan, Jefferson and Emory are good places to train, but they have different cultures, so it comes down to fit. They actually vary widely by department, but as an average they come about to about the same for your resident experience. Your fit is more important than small differences between them, IMO. I know less about the others on your list, except that I once worked with a recent ex-resident from Baylor who was very down on the program (for whatever that's worth).
