Ive, any large, mature leaves will more than likely be lost during the rooting process. I typically cut all those large leaves off when I take the cutting or when the callus is formed and I am about to root it/them. I cut those leaves off so that 1-2" stubs are left. Those stubs will fall off within days.
I will keep my new cuttings in a shaded greenhouse for a week or so and then I move those buckets of cuttings out into pretty much full sun. I probably doesn't matter whether they stay in bright, indirect light, part-sun, or full sun though. The main thing is that you don't want that rooting media to get wet. There are no roots to use the water and wetness will only increase the likelihood of rot. I will spray those small leaves, left at the tip of the cuttings, with water every few days so long as the temperature is above 80F.
