In order to use "null" here you need to tell the system its data type using cast.

As I mentioned in another post, I really don't want to have to specify
the type, but at least this is better than coming up with different
(literal) sentinel values for different types.

For now, the SELECT with purposely empty result set is still (sadly)
winning. If there are more succinct ways to express the SELECT, I'm
certainly open to that too.
