Your degree name (and title) are unimportant. I'd probably suggest going the more flexible route so if you decide you actually don't like the marketing option(s) you aren't stuck with those!
Note that your CV should match the wording on your degree certificate/diploma and transcript, so I wouldn't randomly append terms to it. As noted it's not important anyway - if they care what specific modules you took they will refer to your transcript, and the more important thing will you demonstrating you have developed those skills and then applied them in a practical way through work experience etc.
You don't need a specialist marketing degree to apply for marketing grad roles.
