I think it's a personal choice as to which interests you most or which you feel you would use more in the future. As you say, they all "fit". Personally, I would take the Health one as it would help me individually as well as, if I were going to be a nurse, professionally.

Unless you plan to be a nurse therapist, the counseling one might be interesting but don't know that it would be too practical and, unless you plan to go into management, don't know that the conflict resolution one would be very useful?
