Spider-Man makes a lot of mistakes, and overlooks a lot of very important information that could help him in the future. Though, in the new movie (Spider-Man: No Way Home) He is presented as a young adult, therefor making him quite unwise and immature with making his own decisions, later leading to the death of a loved one.
Hubris
A lot of Spider-Man's poorly chosen actions and emotions/morals get in the way of the safety of his loved ones. ( His aunt, uncle, girlfriend, friends, depending on the universe )
Peripeteia
Peter's reversal of fortune-- one of his loved ones passing away (This scene is supposed to be from the new movie where his aunt dies)
Anagnorisis
Spider-Man's moment of realization-- That he is a threat to his loved ones, and even himself at some point.
Spider-Man's ultimate nemesis is Green Goblin-- Since he rebelled against Peter and his plans to "help" him and the other villains from the other universes
Nemesis
Catharsis
The Catharsis in the movie is having everyone forget who he is, including his girlfriend and other close friends.
