Vibration in rear end
There are several other things which can make a noise. The people you showed the car have the advantage of hearing or feeling the noise that we do not have a chance to do.
A catalytic noise can change with the engine RPM. You can rev up the engine in Park or Neutral and should be able to replicate the noise. If not, then you have a moving part making the noise.
Sometimes the Emergency brake material comes loose from the metal backing and jams inside the rear drum/rotors. It will cause vibration when pulling away from a stop, and eventually will grind into powder.
Rear axle differential clutches. There are friction disks inside some types of rear-ends. A special lube additive makes these work. Sometimes a refill of additive and lube can make marginally performing units more quiet.
U-joints can make noise and vibrate. Its another moving part noise.
The fan clutch can also make noise and vibration. The A/C compressor and compressor clutch bearing can make noise. The A/C clutch operates intermittently depending on pressure and temperature.temperature.
