Baby room need ideas help - neutral

Partner and I have agreed we don’t want to find out the sex of our baby. Problem is we have no idea where to look for ideas on bubs room. Walls will be white with one wall being grey which you face as you walk in the room. Right wall back onto the other bedroom and left has a window to the backyard. We have minimal space and have a chocolate brown couch along the wall the door is on. Any ideas what to do with the walls (shelves/storage) and decor (wall stickers photos pictures etc). Thinking cot will be white with the raised back lower front as it seems more practical for the space we have.
