A classic thing to do is to plant a circle garden around your light.
It's tough to advise on seating, because you didn't show us by the fence. I'd go for where there are mountain views. It looks like you have some and those hills are pretty.
You might plant a redbud or dogwood between the 2 windows.
I'd plant a mix of mountain laurel and native azaleas/rhodos, as foundation plantings.
