Across the line use a type X cap, and 250V is fine. You could (should) add a fuse in between the cap and the line for an extra margin of safety.

I thought the X and Y capacitors were used when a short would be a safety
problem as in a shock hazard. Why would there be a shock hazard if a cap
across the power line shorts? If you use a fuse any concern about a fire is
eliminated. Then why would you need the X cap?

Y is for shock risk, X is for fire risk only.
