FCC Approves 5 Year Satellite Deorbiting Rule

I know how small the debris is relative to the earth. But the sheer number. Would that have any effect on the sun reaching earth and it’s heating / cooling?

No.

To have an effect you need to launch multiple orders of magnitude more mass than we have, and that mass would need to be optimized towards having as large as an effect as possible by being very very thin film positioned so that it is consistently between earth and the sun (or you could add on a few more orders of magnitude).

You can look at proposal for doing this intentionally to get a sense for the scale: https://en.wikipedia.org/wiki/Space_sunshade

No, that's like trying to cool your house with a pinch of dust.

Bus = 0.0002 km²

Earth = 510.1 million km²

(Earth / Bus) / 100 = 25,000,000,000 bus sized satellites needed to cover 1% of the sky.

You're a bit off, you have to calculate the area considering the height of satellites.
