The delays that are observed by app-delay-tracer include everything you mentioned (queuing delay, propagation delay, which is related to packet size), except processing delay. This exception comes from the fact that in NS-3 unless you specifically simulate processing delay (which requires additional models), each function call, no matter how complex, is running in zero simulation time.
