There is a bit of luck in even having any viable materials that work at the required temperature to choose from.

For example, humanity hasn't been able to find a single appropriate material for a superconductor at room temperature/atmospheric pressure despite significant research, but a civilization living below 100 K has a myriad of options to choose from. Superconductors are high technology to us, but if your planet is cold enough then superconducting niobium wire would be a boring household item like copper wire is for us.
