Lawyer jumping in here. Whilst I understand why you might be attracted to certain types of law and not others, I'd say that it is way too early at this stage to make any judgement calls on what you would end up enjoying practising as a lawyer. True, contract law features heavily in the commercial context (particularly if you want to work in biglaw), and I confess I wasn't particularly enamoured studying it in my first year of law school, but it's actually one of those areas that allows for a lot of creativity, which I am starting to believe more and more is a hallmark of a great lawyer.
There is a craftsmanship to drafting and a skilled lawyer in this regard is like an artisan. Even litigating contract law cases is particularly interesting because there is often a wealth of interpretation in those disputes, and the arguments that you put forward can be interesting (and quite important in the wider context of precedents, common law etc.) I've been on both sides of the equation.
Not that I'm pushing contract law or anything, but just citing it as an example of not judging a book by its cover.
(Btw, i should add for clarification that there is no "contract law practice group" in a law firm - it is integrated with the firm's practice groups based on other subject matter, e.g. M&A, telecommunications, banking and finance etc. I had a potential applicant, a law school student, enthuse to me about working in the "contract law practice group" in one of those recruitment events - it demonstrated a real lack of awareness of the commercial reality, not to mention a lack of bother to do a simple Google search on the firm that you are supposedly so "excited" about (or even any other law firm) to reveal that there is no such thing as a "contract law practice group". Needless to say, he did not even make it to the first cut).
