Also, you can investigate job boards like Indeed to see just how in-demand some languages are. I have seen listings recently that require/prefer applicants proficient in languages like Korean, Mandarin, Spanish, and German - among many others.
Anything dealing with being a learned person in any field that requires knowledge and skill has its benefits. During the few months to a year where you can take off you can travel and go research and teach in different regions and places. Your major benefit is employment all over the world. Your greatest benefit is arming the youth with strategies, methods and self empowerment.
