There aren't any cyberpunk face-card decks as game-aid tools I can find...
I've had the same amount of success you've seen to had and while proving a negative is very difficult I think its safe to say there isn't a commercially available product that would meet your criteria. However....
Android:Netrunner cards meet all the criteria
Android:Netrunner is a LCG from Fantasy Flight games that has been going on for a few years now and features: 1)Features no non-human races, there are robots, androids, mechs etc. but no dwarfs or aliens or anything of that nature, 2)Has a unified art style across every single card, and 3)You can view images of cards that are already released (there is a 6 month blackout window card database sites use to not interfere with the retail of the physical product) and decide if you like the style or not before you go buy some cards.
You can take a look at cards at databases like this one which I've linked to show the core set (aka the starter set) of cards.
They can also serve as inspiration for NPCs
Over at Dreadgazebo there is a great article about using Magic:The Gathering cards to create NPCs, magic items, and custom spells. Cards can tell a story through their mechanics, names, and flavor text that you can readily use and Netrunner cards are equally viable for this for a Cyberpunk RPG as MTG cards for D&D.
