I think it is better to get some type of speciality but I don't believe that you major in will lead to only one job. What I would do would be to narrow down to 2/3 job types your search - you are mentionning both finance & marketing for example. Then go on LinkedIn & look for people's profiles with post-university jobs in those fields - look for people with nothing more than 2 years of experience.
Finally take a look at what their degree was & what they did study, it will give you an idea.
I think it can be a good way for you to actually see what people study & where they end up.
Good luck in your search !
