Yes, certainly. That is what tensor equations do, which is why modern
theories of physics are expressed in tensor equations.


For this observer independent description we need a
preferred frame, presumably the frame in which the equations that
describe the universe take their simplest form.

No, not at all. What one needs are tensor equations, as in GR.
