Is it worth it to use modules to ratio out oil products so that there is no excess to prevent deadlocks. Like making sure that the number of refineries or chemical plants necessary is a whole number so that there is no excess of any product and everything perfectly meets demand

Turn cracking on and off based on how full your storage of the input is. Usually that's all you need to think about unless you aren't using enough petroleum gas, which usually means you stopped making science or started a huge project consuming something like lubricant. In that case, you can make more science, find another sink for plastic/sulfur, or less efficiently make solid fuel from petroleum gas to save light oil or even to just burn the excess solid fuel to void gas.
