These people tend to work best where there's a scale of meaning to the job. Education, journalism, documentary film, translation, international projects, science at the seam between disciplines, law that crosses borders, any modern version of teaching or outreach that's genuinely about widening someone's horizon. I'd put it like this: a narrow role tucked inside a single local system rarely takes root with Pluto in Sagittarius. They either fade slowly in such posts, or they stage a quiet revolution and leave to go and build a bridge between worlds instead.
In my experience the roles that suit them are the ones that ask you to assemble a whole out of mismatched pieces. A lecturer running a course that sits between philosophy and history. A journalist writing about another culture from the inside rather than through a tourist's eyes. A lawyer working cases that straddle several jurisdictions. A producer on an educational project who has to understand both the audience and the material. Anything to do with translation tends to come off well — and not only the linguistic kind, but the work of carrying meaning across: between generations, between countries, between professions.
The dangerous side is falling in love with the scale of an idea at the expense of the actual task in front of them. They can spend a long time explaining why their work will change the world and never finish a single concrete piece of it. When that gap drags on, burnout often follows — sometimes a quiet crisis right at the peak of their involvement. From that point they either drop into cynicism, or they rebuild the approach and come back with something more modest but more real. This generation often comes to see that genuine change in the world rarely looks heroic, and almost always asks for patient, unglamorous, everyday work with no big words attached.
