>Gravitational waves are weird
Are they though? I know there is a lot of math behind how exactly gravitational waves behave making specific predictions that stem from GR, but even in the Newtonian sense, something like gravitational waves would necessarily exist. That is, even under Newtonian laws, if a body emits a force like gravity which drops in strength with distance, and if that body moves back and forth in relation to you, you would necessarily experience waves of force.

Not if you take the term "wave" literally. Any action in Newtonian gravity is assumed to occur instantaneously, so while an observer far away from that body would certainly see the gravitational pull varying in time, this would not be the same as a wave traveling through space.
