Back to the original question, if by "midlevel" you mean Physician Assistant, Advanced Practice Nurse, Anesthesiologist Assistant, Podiatrist, Psychiatrist Clinician...
It really depends on your experience and your desires.
If you are already a nurse, and enjoy nursing, then picking one of the advanced practice nurse careers could make a lot of sense. A nurse midwife, a nurse practitioner, a clinical nurse specialist, etc. Lots of ways to move up in your career without having to do a whole lot of coursework and time.
If you have a strong background as an EMT, PT, OT, RT, MA, MHW, or other medical-related career, you may want to think strongly about becoming a physician assistant. PA school is very competitive, however, so you should have a very strong conviction as to what you are doing and why, do very well in all your pre-medicine courses, and find a PA school that really fits you well. If you want to talk about PA school or the PA profession, feel free to message me.
Find what really fits you, and go for it!!! (Or as Dolly Parton once said, "Find out who you really are, and then do it on purpose!") Having a career that really fits you and makes you happy is more important than any other advice. If you're a person with some good life experience, you'll know that to be true.
Best to you in your search! Let me know if I can be of any help.
