One point on perception - doesn’t the sun appear somewhat yellow because the blue light has a stronger tendency to scatter, meaning that the roughly white light of the sun is less blue, with all the blue color of the sky being taken away from the color of the sun?

More or less, yes. That’s also why it appears more red/orange as it gets closer to the horizon from your perspective, since at that oblique angle the light has to pass through more of the atmosphere to get to you and more of it gets scattered or absorbed by particulates in the air.
