> The surface of the moon is 100 m thick blanket of impact debris that has been pulverized over billions of years. Nothing in kind of structure could survive that treatment, regardless of whether it is silicon or carbon based.
Impacts would destroy any conceivable microbes in the immediate vicinity of the impact. But unless an impact was strong enough to sterilize the entire moon all at once, microbes outside the kill radius could subsequently reclaim the impact site. Like plants reclaiming land after a lava flow destroys everything previously living in that spot.
I agree with your other arguments, and believe the moon is sterile.
