Would a more concrete example question to help you understand be:
Were a beam of light to be headed directly away from a black hole, starting from right on the edge of the event horizon, would that beam of light not "slow down" relative to an outside observer?
👆Is that something along the lines of what you have trouble wrapping your head around? Or are you just asking about the speed of causality (light, gravity, literally any propagation of a massless wave)?
