What will it be used for?

Bedroom not office

Not that hard and not that many options.

Nothing in the bump out, except as a space to put folding luggage racks for your guests luggage. Store them folded in the closet when not needed.

Are those shelves flanking the nook?

^ what is flanking the nook? I would put a window seat in there with book shelves running up the sides. A comfy little reading nook. FYI - I love window seats - but I don't have one in my home!

"I’m at a loss with the strange bump out…"

Are you going to build this house??

A window seat would be convenient for guests to lay out clothes, or sit to put on socks without sitting on the bed, or to set other items. A chair might seem charming but a window seat or bench might be be more multipurpose.

Window seats are lovely, but no one I know uses them for reading. I have two in my primary residence and one in my vacation home. In my primary residence they are in hallways and are just places to put things temporarily. The one in my vacation home is in a guest bedroom and they just use it for a place to put clothes etc. while they visit.

I wasn’t even thinking a window seat! sounds lovely.

Window seat with drawers as there is no closet in this room makes sense. I would also do night stands with drawers as there won’t be space for a dresser anywhere
