I have a transformer and rectifier circuit to get the 120 V down to about 12.6 V DC ... I made a buck converter to take the 12.6 V to 5 V.
Note then 10mF and 30 mF are very big unusual capacitors.
I simulated with your values the rectifying/filtering/step down part of the schematic.
Voltage output is about ... 5V, with efficiency around 55% (-> 65%).
For best results, one can use a PFC ... but it is more complicated than simple rectifying.
