Do we know, or have an idea, at what stage or level gravity or other forces can continuously overcome expansion? Or could expansion get to the point where it would tear even objects apart?
Or, is the most direct and short answer, We don't know?
Yes, the measured Hubble parameter tells you how quickly the distance of two points increases, and that can be translated into a small tug. If the simplest concordance cosmology is right the hubble parameter will not ever become so big that everyday objects are ripped apart. But there are the "big rip" models in which H increases dramatically in the future and space expands ever quicker until even the atoms get ripped apart.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
