I mean research essays. You're obviously going to be doing writing in all of your subjects but some arts subjects are heavily research based in their assignments. It's a good skill to have, especially if you plan on going into an honours year.
Journalism in first year has 'articles' but they're not really research based. You might do some light research depending on the topic but it'd be more stuff you'd find on the internet rather in spending hours looking through online journals or books in the library, and it wouldn't make up your entire assignment.
Linguistics when I did it had mostly short answer assignments.
French will probably have language translation essays and maybe a culture essay, but again I don't think it will be anything that will require you to consolidate research skills.
Idk, these are just my thoughts

I also think sociology would go quite well with journalism as both are focusing on different components and issues of society. It could be advantageous to have more insight on the make-up of society as a journalist.
