What if I'm "a couple of standard deviations better" at "giving incredibly good feedback in a variety of areas" too but lack the rest of Steve Jobs' talents so this "rare and hard to identify ability" feels like the only thing I'm really good at? How do I start a career around this?
Well, if you truly have that talent, you can probably be a highly successful consultant. Just start charging people for advice. You could start by offering advice for reviews to targeted high profile clients who need it, then seek referrals.
However, the first question to ask yourself is whether you really have that talent. If no one at all offers to pay, you likely don't. I don't mean you're bad at advice, rather instead that you're just not earth shatteringly good at it. Lots of people are good at advice without being able to build a career specifically around that.
Oh also, to be a highly effective consultant other skills would be required too of course. Empathy, business thinking, etc.
Jobs was only able to build a career around it by building companies around him. That's one way, but not easy, and also he had other talents and compulsions and vices that made his path what it was.
