What if the cable is brand new and it still bounces and clicks? Is it more likely that the manufacturers didn't put enough lube on the cable or that the speedo itself is failing?

Sometimes it hard to tell. You can unhook the cable from the speedometer & drive it & see if it still clicks.
I have used a drill to test speedometers & cables in the past. It may give you an idea. Easier to troubleshoot noises if the car isn’t moving and the engine is off.
