Actually, your are incorrect about physics not being an employable major. It is one of the best in the sciences and close to engineering. i speak form 32 years experience as a physics professor who has seen many students go off and work instead of going to graduate school. The nice thing about physics is that you learn a broad range of fields all of which have engineering offshoots. You will also learn computing at some level and a number of physics majors I know are now working the software industry. You can go to medical school if you like, or law school or business school. Bottom line is that if you like physics then major in it and use it to launch your career in whichever direction you wish.
As a secondary comment, please don’t choose to go to medical school just because you will be employable. We don’t need physicians who are not committed to their profession for any reasons better than expediency.
