Choose the course of study which you can get the best grades in and can enjoy the most. Unless you are rather specifically studying something (e. g. you want to be a doctor or an engineer), the subject of most Bachelor's degrees doesn't matter, even when you are looking to go to graduate school.
For medicine, it helps to have a background in Biology, Chemistry, or the like, but I knew a guy with a BA in Economics who went to medical school. It's not impossible, although you need to take the prerequisites either way. Same thing with engineering; if you want an MS in, say, civil engineering, you will need a lot of background courses but there's no law saying those can't be a part of a minor or a double major as you get a Bachelor's in something different.
