OOP's answer is a bit silly, but the question is good... The answer that I want to give right now is "translation, subtitling/captioning, recording audio descriptions, language teaching for teenagers and adults, and something related to linguistics" — so, literally just the things that I already want to do with my life, and I can imagine many ways in which these jobs are vital for society.

...But it's like, if there's only limited spots for these jobs, because there's a more pressing need for people to find other jobs, and jobs in this society are assigned based on objective merit and formal qualifications above personal interest — then I would be perfectly happy to work as something else, and only fill in for these preferred jobs when there's a shortage in one of them, or perhaps "chiming in" during my time of rest.

All things considered, I feel like I could probably work most jobs on some level, provided that I'm given adequate training and the jobs are made accessible — which I'd reckon would be the case, since this would not be an economic system that needs to marginalize certain groups out of the workforce in order to sustain itself, nor would it be an economic system where overqualification is an endemic feature.

So I guess the sky's the limit, then.
