I think the one difference with your number 2 is Peter saved their asses and got the guy arrested. While also saving the city in the process. It's one thing to go off do something with his tech he gave him while also causing a terrible accident and when the feds were in on it. But vulture was still moving unchecked. And he did it on his own without anyone helping him
My issue with it, though, was that he didn't demonstrate that he learned anything from his first failure, he just tried the exact same thing again and luckily succeeded with it the second time.
If they had had Peter use teamwork with Happy/Iron-Man/the FBI in some way in the 3rd act, it would have made more sense to me because it would have shown that he took Tony's chastisement to heart and matured from the half-cocked youngster he was at the beginning of the film.
Instead, what we basically got from Tony in the end was, "Disobey me all you want, as long as you get results". Which seems like a weird lesson for a mentor/father-figure to be imparting to his charge.
