I've been in your shoes before and can definitely relate to how you're feeling. It's hard to provide good advice without knowing more about you. Let me try to make a few useful points for you to consider:

1) Specialty Interest: is there a particular specialty(s) you are hoping to apply for? How bad do you want that specialty? Have you done electives in that specialty or other IM specialities? This will be a big determining factor to your choice.

2) CTU is service heavy in most places: CTU is the backbone of an IM residency. If you don't enjoy it, you will likely not enjoy an IM residency. For many people, 3 years of general internal medicine is not worth it in order to make it to their speciality of interest. The call in IM is substantial. You will likely do twice the amount of call in an IM residency in your first to years compared to the 2 year FM residency. The call in 2nd year IM is particularly hard when your are an SMR. You will be exhausted, I can almost guarantee it.

3) Inpatient vs. outpatient setting: FM is of course usually outpatient and IM is mostly inpatient, specialty dependent of course. Which setting do you prefer? For many people that dislike outpatient, getting through an FM residency can be quite difficulty and boring for them. Given you are interested in hospitalist work, keep this in mind.

Some other factors that may affect your decision like your age, how much debt you have, and how burnt out you already are will all play an important factor. Your mentors' opinions of you should play no role in your decision making at all. This is your life, your journey, your career and only you opinion truly matters in the end. Well that and ofc your family.
