As discussed in person, I'm pretty sure this was user error (although the API might make this more confusing than it should be).
If you have a VariableLayoutReflection for gRWBuffer, it effectively has a type of RWStructuredBuffer<LightCB>[5].
If you ask that type for its "element type" the result is RWStructuredBuffer<LightCB> and if you ask that type for its size in bytes, the answer is 0 because a RWStructuredBuffer consumes no storage in "ordinary" memory (e.g., when used as a member in a CB).
In this case what a user probably wants is someShaderParameter->getType()->unwrapArray()->getElementType(), so that they can drill down to the resource type and get its element type.
I'm going to close this, and we can re-open it if I turn out to be wrong.
