If you read about the CAM rhythm again, seems that by the natural timing, Semps would love Morning sun and partial shade in the afternoon.
@ricos One study thats part of the info im using to write this talks about Semps being generally found in very shallow soil as in 1.25 to 2.5 inchs so that would be extremely well draining but yes the wild ones are usually near something for some shade part of the day, a rock, deadfall or near other taller plants etc.
