"But Sauron struck too soon, before his own power was rebuilt" (Appendix A)
The idea that Sauron could somehow flee to Middle-earth (again, why would the Númenóreans exile him back to his own lands?) and immediately, spontaneously restart his military operations is not supported in the text. In fact, the opposite was true - his armies weakened in his absence.
Given that the Uruk-hai and the Olog-hai were not bred until the Third Age, we can hardly know for sure that Sauron would inevitably develop them in the Second under different circumstances. What do you mean by "black uruks"? As far as I'm aware that's just another name for "Uruk-hai."
You also seem to think that the Mumakil are some kind of superweapon, but beyond their use at the Pelennor Fields where the Haradrim and their oliphaunts were still defeated and destroyed I see no evidence of that.

The Balrog wasn't discovered until the Third Age. The events we're talking about here would have happened in the Second Age.

A lack of Sauron in the Third Age would change events in the Third Age so drastically that we can't be sure any of them would still be recognisable. For all we know, Smaug might never have come to Erebor even if it was founded - it only became rich after the abandonment of the Grey Mountains after all, and the Cold-drakes might never have come to the Grey Mountains in a world devoid of Sauron for any number of reasons. Similarly, why would the Wizards be in Middle-earth in the Third Age if Sauron was not there? Resisting him was the entire reason they were sent.
