You should ask Georgetown what usefulness there is with an MS in physiology and biophysics if you aren't going to be an MD/DO. They should have plenty of examples of successful alumni who didn't go to medical school but did do something with the MS. That answer alone should help you figure out if the value of the degree is worth it. Same thing for that MS in biotech at Hopkins. The degree means nothing if you don't really move towards medical school unless there are clear resources for career preparation outside medicine.
Since the Georgetown SMP was established, many schools (with medical schools or not) have developed postbac programs. Some are modeled after Georgetown while others are not. If you are not gung ho about going to Georgetown for medical school, I don't advise you to necessarily go do their SMP because you'll probably repeat those courses if you got into another medical school. (Thank you to the curriculum innovators at other schools.) Many other programs are focused on the rigorous science coursework itself, and may offer you a certificate (less expensive). So for anyone in admissions, they probably know which schools have strong preparation for medical school. They probably know which schools have modelled their postbac/SMP on others and their track records too. In the end, the institution gives many admissions experts the context needed to know how rigorous the science coursework was, how much mentoring and support a student had access to, and how likely the student was going to succeed in their curriculum. Those are the things that matter most that frame your success in such a program.
