I agree it's not a force, but it is valid to view it as an interaction involving gravitons and field theory. Any unified, fundamental (quantum-mechanical, probably string theory) solution would have it as that rather than the relativity explanation (which is valid at larger scales).
If you are going by field theory, weight is the force that a gravitational field produces. If you go by relativity, as you say, the force is a psuedoforce [i.e. not real] based on our frame of reference [much like centrifugal force].
