[X-Men] Are there mutants with seemingly "useless" mutations/superpowers, and if so, what jobs do they serve on their missions/teams?

I mean, like, for example, what about a character who can only make their fingernails grow longer, and that's it? Does that character go on missions with the rest of the team or are they more inclined to play some sort of secretarial role inside of Professor X's office? Thanks.

Not every Mutant is part of the X-Men. Xavier made the school just for mutants to have normal lives and learn how to deal with their powers with the X-Men being a side thing that is both a choice and something that the heads of the school need to approve on. Majority of Mutants just live their normal lives to the best of their abilities.
