Hey!
Now, with 2000 shadow rays, trace depth 10, I got what I wanted. fg: 650. min-0 max - 0. gi accuracy is at 220.
the sampling for the area light is what determines the grainyness. its at min-5 max-17. however, it is now a bit washed out. I will reduce the intensity of the light next.

time for render: 45 minutes
