I also agree with Mac. Ideally you want the bed on a wall opposite of where you walk in. The other option is putting the bed on the other window wall. So the bed is facing the dresser. My master bedroom is similar to that layout. I had remodels the room though and replaced the one window you have in that wall with 2 smaller narrow windows I’ve removed the nightstands. I know you said it’s not to scale so not sure if you even have the ability to put the bed on that wall or how high the existing window is.

As far as lighting. Over my bed I put 2ea low voltage recessed mr-16 halogen lights with a smaller hole. The light shines straight down over the head/ upper body area. They are in dimmers as well. My headboard is metal and open so the switches are behind the headboard.
