How far down does a person own, on their property? I mean, keeping things (relatively) simple-- and residential-- and assuming you respect the water table, utilities, etc?

In most cases, you own to the center of the earth. But you may not own the rights to extract those minerals.

Also, it’s often moot because some part of the government will require you to pull permits to kick a rock in your backyard.
