I like to use the "Blue Goo", otherwise known as Sta-Lube boat trailer wheel bearing grease.
Available at most auto parts stores. I also use that to grease the threads of cable adjusters, pedal threads, all bolt threads, etc.
To lube wires, I use a light coat of Phil Wood grease on the wire and a shot of Tri-Flow in the housing.
Bike shop for the Phil grease and Tri-Flow is also at auto parts stores.
