F = dp/dt
If you are travelling a geodesic, your momentum does not change.
Therefore if dp/dt=0, F=0.

Actual gravity is the curving of spacetime. Under Newton's Law of
Inertia you follow a geodesic unless forced elsewhere. If your geodesic
intersects, say, the surface of the earth which resists deformation, the
surface exerts a force against you forcing you off your geodesic.

Newton's approximates the curve in the metric with a made up force.
Newton gives simpler calculation. That is fine if the approximation is
good enough. Just keep in mind it is an approximation.
