What drive is available?
What budget?
Size?
Transient ratings?
Yes, double-switching would seem likely to work.
Snubber value is unclear, presumably you want it smaller than would be irritating for AC operation. So, not, like, >10uF and 1 ohm or something, roughly.
The low voltage operation doesn't buy you much, the switch still needs to be rated for full V and I. Or more, if transients are expected (the 250V is mains-connected). A normal "250VAC" relay includes that in its UL rating, AFAIK (the '250V' is a type rating and the actual breakdown is some kV?). Or hmm, maybe not, that would be something a disconnect would need to be rated by, but not necessarily a relay? Or contactor? Look up the standards to be sure.
If you need absolute least cost, and safety is not a concern, then just [ab]use whatever relay and be done. If you need UL approval, buy the 250V AC/DC relay and be done.
If this is one-offs, what are you even worrying about, you've already spent the $10 difference thinking about it!
