I know that Ph.D.'s in leadership are practically a dime a dozen these days, but I found Carolina University's explanation of their program to be pretty well considered. They say that there are tracks in Healthcare Administration, Justice, Ministry Administration and general/no concentration, although it isn't entirely clear for all the tracks from the curriculum posted what the courses are. There's a required residency (only a week, but better than nothing, and not a months long one either) and the tuition is a not too outrageous $570/credit hour. They're accredited by TRACS through 2030, which I see as a bit of a drawback (though less than it used to be) and their accreditation page interestingly says, "CU has additional accreditation in mind as part of our strategic plan for the future." The name of the university is pretty good too.
