The Daredevil season 2 and Spider-Man conundrum:
The answer to why Spider-Man doesn't even cause a ripple in Mayor Fisk's NYC goes back to the end of No Way Home. The Spell wiped out all memory of any connection between Peter Parker and Spider-Man. But MJ in the coffee shop doesn't recognize Peter as a classmate either. It appears that the Spell actually completely removed all memories of Peter Parker.
Consider Peter's situation post NWH, he is completely alone, no friends, no family, no mentor, no support of any kind. He might even have had to get a day job.
But it was his relationship with Tony Stark, with the Avengers, with Nick Fury that Mysterio used to trick Peter and eventually resulted in his unmasking. Peter decided to continue as Spider-Man but could have real concerns about teaming up with other superheroes in the future. So he could be avoiding the other heros in NYC.
He may have even gotten more discreet in his heroing. Sticking to a lower profile as he intercepts criminals. In and out of situations as quickly as possible.
Another factor is Spider-Man's wall crawling which keeps him high off the streets and how quickly and quietly he swings through the city.
There's a possibility that he isn't considered a vigilante because he was part of Tony's team supporting the Sokovia Accords, and may have signed them. Combined this could account for Fisk's Vigilante Task force not targeting Spider-Man.
Matt Murdock's memories of Peter are gone too. He would even remember any relationship with Spider-Man. So he isn't likely to seek him out.
