Elective, IM vs Family med

Hey guys, US IMG here. Obviously USCE is crucial. I think I want to go into family medicine, but also may want to go into internal medicine, im unsure. Anways, im going to apply for an elective for this summer, but im not sure which to go for. I do prefer family medicine slightly sure, but there are WAY more internal med opportunities for electives.

I guess my question is, what do you guys think about if I did an internal med rotation, if family med ends up being my top choice, and I at somewhat of a disadvantage with that, since I wouldn't have done an elective in what I exactly want to do (as if we are meant to KNOW).
