I don't get the claim that this movie doesn't have a plot to it. It's a direct follow up to FFH where Peter attempts to recruit Strange to bring back his secret identity but it goes wrong and villains from across the multiverse show up. Yes, it's a celebration of live action Spidey in general but the reason the movie is so good is because all of it contributes to the growth of Tom's character and directly deals with the consequences of the last film and shows him what it means to be Spider-Man
