Try different values and see. I would start out with 2 uF and a smaller 0.1 uF bypass, and see what you think. One of the units in use and being experimented with is using a 10 uF cap, bypassed with a 0.22 uF stacked foil low inductance cap.
If the transformer steps down and the second one steps back up, then the caps will only see some fraction of the full AC line voltages, and any transients will be blunted by the transformer inductance. So full X or Y rated caps are not absolutely necessary. How close you want to cut the margin depends on how much the step down and back up is. Too much, and you need gobs of current capacity to retain any amount of wattage capacity, too little step down, and you will need to use full AC line rated caps for safety.
See Steve Eddy's post:

the second diagram may be what you seek.
