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.

There are two parts in your question. For now, only answer for the first part.
NoteNote then 10mF and 30 mF are very big unusual capacitors.

I simulated with your values the rectifying/filtering/step down part of the schematic.
I used a 2 A current as a load.

Voltage output is about ... 5V (!) and, with efficiency is around 15%.
