First, I'd point out that for your character to have come from an organ growing facility, that facility would have been secretly doing something else, as "wimps", the human bodies grown for organ replacements, are essentially lobotomized and will not and cannot function as characters of any type. It just means your character musta been part of some "Well, why don't we try making super soldiers or something" secret operation.
Any kind of drones you may have are great for RP as they can be "pseudo-characters". They aren't smart enough to be NPCs, but they can have quirks and such.
Really, all kinds of augmentation can be good bits of RP as well. This may not fit your character, but let me explain with a character I made. I had a hacker named Grenadine who was a transhumanist-- She believes augmentation was basically the next step of human evolution, just the natural course of things. She had two cybernetic arms, and there was a lot of characterization in what they were augmented with, how she took care of them, and where she bought them. Since in Shadowrun, as with any modern setting, everything is a brand.
This can apply to basically any piece of gear, too. There's a big difference in roleplay between "My character has cyberarms and cyberlegs with high AGI and Gymnastics Optimization" and "My character's limbs are all sleek, black models from Saeder-Krupp's Akrobat line, known for their incredible flexibility and durability."
