I guess the force is acting weakly in opposition to gravity. Am I correct?
This is correct. The energy density of the dark energy is overwhelmed by gravitational attraction over these kinds of distances.
Perhaps over even larger distances. The distance between the Milky Way and Andromeda is not affected by dark energy. In fact, the entire Virgo Supercluster of galaxies may be unaffected by dark energy.
It is a very weak effect. It's just that the universe is quite big. Have I mentioned that? It deserves mentioning again.
