All good questions. Fast answer: we have no clue. Until we have a good quantum theory of gravity, we can't explain how it affects the curvature of spacetime at the quantum level. All the current quantum gravity theories, i.e. loop quantum gravity, string theory, etc... work if you squint just right, otherwise they fall apart really fast. Spacetime has a bunch of episodes on going theories. A very large elephant in the room is, a lot of these ideas don't have a method of testing. And sure, a lot of theories start out without a practical method until decades later where technology can catch up, but we don't even have a theoretical test to start with! Spacetime recently did an episode touching on some of your thoughts at the classical level and even then it's... relative[0].

>>> we don't even have a theoretical test to start with Every quantum computing calculation, is a desktop quantum experiment ;) Non-Gaussianity as a signature of a quantum theory of gravity https://arxiv.org/abs/2004.01189 https://arxiv.org/abs/2004.01189 Another cool aspect of the optomechanical tabletop device research was that it wasn't entirely fruitless at all. Although the original mission of finding gravity in quantum space may have failed. The behavior exhibited was so extremely non-classical that an explosion of waveguide manipulating metamaterials was born!
