He would probably be more world - weary. Being exposed to S.H.I.E.L.D.'s darker side and the global threats it deals with from a young age would make Peter less naive. He would see the world as a more dangerous place, and his sense of humor might be a bit more sardonic, a way to cope with the weight of the responsibilities he's been given.
Peter's life would change drastically. He would have access to S.H.I.E.L.D.'s vast network. He could get better training in combat and espionage, which would make him a more well - rounded superhero. Also, he might have to move to a more secure location, which could mean leaving his friends and normal life behind, at least to some extent.
The fanfiction might have Peter being raised in a more militaristic environment. Nick Fury could instill in him a sense of duty that is more in line with S.H.I.E.L.D.'s global security goals. For example, Peter might be trained to think of the bigger picture when using his powers, not just saving the neighborhood but also preventing international threats. This could lead to some really interesting crossovers with other Marvel characters in the S.H.I.E.L.D. universe.

His relationship with MJ would likely become more protective. MJ might worry more about Peter and be more involved in his day - to - day life. She could also be his eyes in certain situations, like describing the layout of a new place or a new threat. With Ned, Ned would probably be more hands - on in helping Peter with technology. He might modify Peter's web - shooters to have more audio or tactile feedback.
His personality might become more reclusive. Since spiders are often solitary creatures, Peter could start to withdraw from his social circle. He might be less likely to engage in his usual banter with his friends at school. Instead, he'd be more focused on his new - found spider instincts, like finding quiet places to rest or being more aware of his surroundings in a way that makes him seem aloof to others.
His personality might become more in touch with his emotions. As a girl, Peter could be more empathetic and sensitive. He might also be more cautious in some situations, as society often treats girls differently. For example, he might not be as quick to jump into a fight without thinking about the consequences more carefully.
His relationship with MJ would become very different. Instead of a romantic partner, she might become more of a protective caretaker. She would have to deal with a baby - like Peter, which could be both challenging and endearing.
His relationship with Aunt May could become strained. Since becoming a Savitar fan, Peter might be more reckless in his pursuit of power. Aunt May, who is used to the more cautious Peter, would be worried. His friends like Ned and MJ would also be concerned. Ned might try to talk him out of it, fearing that Peter is getting in over his head. MJ, on the other hand, might be intrigued but also worried about the changes in Peter.
