Most modern cables are Teflon lined i.e. they don't need lubrication to function any lubrication will provide corrosion protection only.
Making up cables is a most useful skill - do you plan using stainless wire? And Teflon lined sheaths? Or the easier to solder & cheaper ordinary steel? If you intend lubing them, you mIght as well go old school & just use the steel ones.
If I don’t have any I make my own out of the shank of a bolt. Drill the hole for the cable prior to cutting the length, it’s easier to hold while drilling
