If the Moon were replaced by a black hole of its same mass, we wouldn't even notice except that the night sky would become moonless and we wouldn't have eclipses any more. The tides would keep happening as usual.

It will evaporate relatively immediately. So no tides.

It will take longer than the age of the universe to evaporate. So tides. For a while.

Moonlight is actually a very important influence in many natural cycles, all of which would be disrupted.

And as a motivator for both our intellectual curiosity and our scientific curiosity, the lack of a detailed moon in our night sky would have retarded the development of human civilization.
