Doesn't the paladin smite ability only allow smiting with paladin spells?
I wouldn't read it that way. I would say, "there's no such thing as paladin-specific spell slots, they're just spell slots, so you can smite with anything except maybe Warlock slots, because those are separate." It turns out that Jeremy Crawford would go even farther than that:

@jaa0109 "Can Paladins use Warlock spell slots as a way to utilize Smite?"
Yes.
