So we’re 0.0006% lighter when the Moon is overhead?

Yes, unfortunately not enough to affect the scale when you are weighing yourself.

Do you think if Sun was close enough, but it somehow didn’t affect Earth itself, would we be a lot lighter?

Sure, if you brought the sun close enough, you would start to float up towards it instead of being held down to the earth.
Of course, the entire earth would be ripped apart as a result of this, but you would definitely feel light on your feet as everything around you was being destroyed.

Just to put this in perspective, you are also 0.0006% lighter if you climb 20 meters further from the center of the earth.

You're also 0.5% lighter by moving from one of the poles to the equator, because of centrifugal forces and because the Earth bulges at the equator.
