You are right. My response came off a bit biased and harsh.
I just have dealt with so many people who commonly use the phrase, "I would rather do this, but I think doing this other thing will help my application more." I think you could probably do just about anything, and it can help your application. Might even make you more unique. So do what you would rather do.
To the OP. Go abroad. Do a medical or a non-medical one if you choose to. Literally half of my secondaries (and I'm sure most schools out there) have an essay about working with different cultures. Study abroad, in whatever capacity you choose, will help you answer this question and can be used to cover other similar questions in essays and interviews.
So, I believe studying abroad will really help your app and be a great experience..
