I think that the translation from 2 to 3 dimensions is what gets me. The trampoline example makes sense. But when I try to go 3D, I can only imagine it like a pool, where I'm displacing something else. But another response said that matter doesn't displace spacetime. And you said that a dot on the grid isn't separate from the grid.

I spacetime more like a magnetic field? Defining contours and routes, as well as permeating things that are in its influence?

Spacetime is the trampoline. The universe is the trampoline. All you do is move through it like you would move over a trampoline.
