Is there any advantage to choosing specifically the center point of the pixel to be the sampling position?

I don't think choosing the centre point of the pixel gives any specific advantage aside from ensuring your samples are distributed evenly. It seems you'd get equally good results by consistently choosing (x + 0.25, y + 0.25) from each pixel.

Is that the equivalent of choosing any arbitrary point inside the pixel so long as you choose that point for every pixel sampled?

So you only choose to color the triangles that the sample point is inside? Do you have to go through a list of all the triangles?
