I thought the method should return a serialized JSON Array, but I'm not sure if that's the only requirement.

I feel like the cacheable=true option is important for performance, but I’m not completely confident if it’s necessary for this specific method.

I remember practicing a question about returning data in Lightning components, but I can't recall if it has to be a JSON Object or something else.
