3. Alien Symbiote
Putting Spider-Man straight into the black suit would be an interesting move, and it's popular enough that the backlash from diehard comic book fans wouldn't be too great. It could explained in the reboot that Peter discovered it shortly after the battle of New York, and would also allow that movie to then introduce Venom, thereby setting up his spinoff. This obviously wouldn't be the first time that the black suit has been seen on the big screen, but Peter did don a cloth version of this costume following the events of Civil War, so it's possible the same happens here. Ultimately though, it's seems far more likely that Spidey will return with this alien symbiote after he and The Avengers battle Thanos in Infinity War.
