But one might not immediately notice missing parameters to a
function, i.e. the caller forgot an argument.

But a reader immediately knows that the function takes arguments
which are at the moment unused. I find that clearer.

See above. It's not a big advantage, but it's clearer and can
prevent problems in the future. And to me the void doesn't look
too bad, but that's a matter of opinion of course.
