In my opinion, Skybreakers would make a horrifying policing force for what I'd subjectively consider generally upholding good. Their oaths are much more aligned to becoming the perfect gangster, or a highly authoritarian government's policing force—again, subjectivity; they'd uphold law well in such militaristic societies efficiently and mostly unwaveringly, just not my style of what an upholder of justice for civilians should be. Much better for internal affairs or military policing, for example, rather than the public. Their dedication to higher-ups over the flexible nature of morality would, in my opinion, make them the worst Order as a policing force. I believe that Windrunners and Edgedancers make much better forces for upholding good. As well as Willshapers to a niche extent (more higher crime than regular police calls), and Elsecallers for things like white-collar crime and detective work.
That said, this is all subjective. For example:
I'd argue that Lightweavers would also make excellent therapists, although I do agree that Edgedancers would also make great therapists. They'd (Edgedancers) also make great CPS-like agents in my opinion. And Dustbringers could make great addiction counselors (their oaths seem to require mastery upon destructive forces). Actually, now that I think about it, I think every Order could make a great therapist or counselor of some kind given that they need to be broken to become Radiants to begin with.
Now I'm thinking about how cool it would be to choose a therapist, psychologist, counselor, etc. and filtering by Radiant Order. I hope that's one of Kaladin's legacies
All 10 Orders would make great engineers, artists, performers, businessmen, and pretty much anything else. Honestly, I think a more interesting question is which Orders would be poorly suited to a certain career or societal role? It seems like you can always make an argument for an Order being good at what sounds like something that goes against their oaths. My answer being that I think Skybreakers should not be a policing force for the public, but rather for internal affairs as well as being lawyers, judges, and jury members (alongside Elsecallers).
And then there's Bondsmiths. They'd be good at everything that I can think of lol.
