What about a king on the window wall?....A smaller desk could also serve as a nightstand...

I would to add that the window next to my bed is overlooking my neighbor’s laundry room and powder room. 🤔😳 so maybe curtain sheer in morning, black out curtain at night?

The grey squares are mirror (which i would also use a similar trim to the windows at the top and bottom in order to make it appear as if it is another window. The orange color are curtain placement (i would recommend floor to ceiling to make the 8ft ceilings look taller). and blue in furniture. the benefit of one versus the other is in A - this is the most dramatic appearance. it is literally the first place you see. and it gives you space at the end to do anything you might want (add a chair to read, or a yoga mat if you are into that) without blocking a door (this is important if there is more than one person in the room. B is second best as the next spot your eye goes to but it doesnt leave as much room.

​Okay so your 2 options are to place a small single sized bed right as you enter so the length is parallel to the closets and you would be required to step on the ledge to go around to the side opposite the windows.  2nd option is what I would do which is to put a single bed on the ledge then place lifts/bed risers under the 2 legs that are off the ledge.  You will also have more under bed storage with option 2.  And if you can't find the exact height of the ledge in bed risers then just head to your hardware store and buy some wood cut into squares that is the right height.  I doubled upon risers in my own home because I wanted to store something large under the bed.
