The only way I could accept Felicia as a hacker would be in the context of the aftermath of ASM2, with the Felicia introduced in that movie trying to expose Oscorp for its role in pushing Max Dillon and Harry Osborn to such desperate extremes that they became villains, intersecting with Peter/Spider-Man (offscreen) fighting Oscorp after finding out that Norman Osborn was behind his parents' deaths.
The spider is always on the hunt.
Felicia being a hacker is probably the best way to modernize her (what kind of thief risks leaving DNA evidence and getting caught on camera?)
It's one of those things that "makes sense" in reality, but is generally anti-cinematic, as well as it opens questions about certain skills she has.
To give you a example, look at Scott Lang. He is a burglar and has hacking skills and a team. By making him a burglar the movie establishes his skills and abilities to perform a heist. Sure, he requires some extra training to make him more physically capable, but by making him a famous burglar it establishes to the audience that he is someone with certain special skills and knowledge that the general population doesn't.
Compare that to this script. She's a hacker, with no physical skills beyond that. This version gives her powers through making her a cyborg, but all that physical knowledge and skills are given to her too, we assume. Instead of showing us her skills, they just tell us and goes the easy way to justify why she has them.
Who is also the voice of Felicia "Black Cat" Hardy in the PS4 Spider-Man game and has provided the voice of Carol Danvers in Future Avengers. I bring this up because guess who else voiced both Felicia Hardy and Carol Danvers in previous Marvel animated adaptations . . . Jennifer Hale! (90s Spider-Man for Felicia, and Avengers: Earth's Mightiest Heroes for Carol.)
The spider is always on the hunt.
Felicia can look fierce and gentle at the same time, all while still looking sexy...
