Nothing to do with control wheel or sidestick.
The cockpit displays/warnings philosophy for a given aircraft has to be developed to be internally consistent. however, provided the basic regulations are followed, there is no single required philosophy. So one manufacturer can use lights, one aurals, and neither is right or wrong. provided each works in the context of the rest of the cockpit systems, it's all good.
