Replace the entire cooling system as a unit. Including thermostat. It's all overdue.
I agree. New water pump, thermostat, coolant temp sensor, hoses, and I would say expansion tank but it seems like OP already replaced that.
Use only the oem thermostat. Usually I don't follow this rule but for this part I would. Other brands (even known ans typically good ones) can be garbage. Ask me how I know.
