The Netflix shows are extremely divergent - as all good modern TV is. Even from each other, I'd have a lot harder time placing a through line. If anything they follow the 'Premium Channel Crime Drama Formula' which is a lot less specific and a lot more about being tortured and enduring than being a jerk and learning to be less of one.
In all these series, we meet the hero who is already very capable, who already has their powers, and we unravel over time how they got that way, what their threshold crossing was, because they're already way past it. You can look at it from another angle as Matt crosses a new threshold into the devil persona, JJ into the return of Purple Man's shadow, Cage into Cottonmouth's sights, but all these are about the antagonist and not so much about the hero's entering a new phase or location or paradigm. They do of course follow the Hero's journey loosely, but their return from adventure to their own world is equally as abstract, and what they bring back with them is usually the biggest status quo change, that is, their most heroic persona, which for JJ and Cage isn't really all that heroic, honestly.
This also allows them to more easily transition to a Season 2, for something like Daredevil who really can re-do a lot of the beats from Season 1, just with a different angle or scope, and it still works, so long as the angle is fresh enough, and Punisher, and to a lesser degree Elektra, definitely were.
