Well, there's two schools of thought in 5e on this. Either double up cyberware and adept powers to get super uber awesome at some thing, better than anyone could ever be solely thru cyber or magic alone.... and using cyber/bio to gain abilities so that you don't have to spend adept powers on it.
As of 6we, the first school of thought is more or less extinct. You can't ever get more than +4 bonus dice to any skill test, so there's no "stacking cyber and magic to do what neither could do alone". Pretty much leaves the 2nd avenue.
You want to do fighting and you want to do sneaking. You can use augmentations to shore up the option between the two to be your secondary facet and use adept powers for the primary.
Fighting secondary: Get something like bone lacing. You won't need to spend power points on killing hands, and of course it gives defensive bonuses as well.
Sneaking secondary: A Reflex Recorder for Sneaking would be a great buy, allowing you to buy more bonus dice via Adept powers for your Close Combat and/or Firearms skills.
