Larger rotors can help to make them work better.

Cable also has the risk of water from snow in the cable and freezing.

If the bike comes with mechanical brakes, just try out, upgrade rotors if needed and then go to hydraulic if needed. Or be happy with them the way they are. Don't sweat it, they are an easy upgrade if needed.
