All cables are not created equal. But I've never come across any that are specific to a groupset. Campy have slightly smaller anchor "buttons". Road and MTB (well, flat bar...) brakes use different anchor buttons. I seem to remember some DT shifters with a different shape/orientation than the others. Like a flat bar brake but smaller.
Brake cables are different from shifter cables.
The rest is optional.
Die-drawn?
Teflon-coated?
Stainless?
Galvanized?
They all have their pros and cons, and the difference is rarely critical.
