Ronald Reagan had been a governor. I agree that it is hardly a prerequisite for the presidency, but some executive experience is a very good thing. Some experience in Washington is a good thing. People skills are important, also. And of course we want a President with vision.
Reagan was a governor, of a state bigger and more complex than most countries. So, what’s the take away?
That Reagan did not micro manage California, nor did he micro manage or try to micro manage the country. He was a visionary in both offices.
And of all of those traits mentioned in your post, vision is far and away the most important. Management is a skill set you can hire. Vision is something you either have, or you don’t. Period.
