With so many street kid or nomad archetype characters in gaming/fiction in general, I'm excited to see what the corporate background can offer. Unless the game changes my mind, 2077's corruption up top seems more intriguing than any street-level gangs.
I'm assuming most will go with street kid to get that "rags to riches" story.
That would be a viable option and probably the option most aligning with the general plot or idea of you "rising up".
For me, I think, it is still the corporate background however. Since with it I doubt you obviously come from a background of being high up in a specific or key corporation we encounter in the game (what's the point of making a name in NC for yourself then if you are a big thing elsewhere?), I think I like the corporate world and it will be interesting to see what kinds of references and (prior) contacts you might encounter with such a background.
