You do not need to use X/Y safety for those 3nF unless you want to. Y safety is there to ensure you do not become connected to Mains. In this case the caps are on the secondary side of the transformer so even if they break down you do not become exposed to MAINs, it would take both transformer and the cap to fail short and this is a double failure.
Simple cap with appropriate voltage rating will do.
