A double casement window can be shaded really well nowadays, optionally also automated. A double casement window of usual size including motorized external shading costs about 3K for new construction, afterwards rather 4.5 - 5K. If the reveals can be angled, incredibly beautiful light comes in. Only if money is tight, possibly leave it out, otherwise definitely include it.
And what is really loud anyway? Rain pattering on the glass can also be soothing (like for example the sound of waves), you just have to associate the noise with something positive (I do this with the baby crying from the apartment below me, now I always get in a good mood when the baby cries :D )
