And what we see on-screen is that all Borg encounters, starting in FC, had Borg ships smaller and weaker than the one in TNG.

It was still depicted as an utterly hopeless battle.
Perhaps you can say that the cube in FC was "weaker" than the one in BOBW because they were at least able to scratch the hull (although this is better explained by the fact that Starfleet has new weaponry), but the fleet still stood no chance. It was certainly not
weak. Yet the ones in VOY are the same type of cube.
