Between the width of all the windows, the squatness of the length and the ceiling slope, I'd stick with either Solar or Roman shades or TDBU Cellular shades. While it's hard to tell from the pic, I don't think you have enough wall space for stack back either, if you went with curtains. You'd need a lot of width to either cover, or look like it'll cover, all that width.

Traverse style rod would look and function best so custom for sure. Contact your local trusted source that can provide a one stop shop for fabric, manufacturing and installation.

Not sure if this is any additional help to get a better sense of the wall.

IMO no drapes in that very sleek space but if you want drapes they will be best hung as high as possible before the ceiling begins to slope so kind of like this I would do nice simple full linen drapes and please add some art to those walls the space needs life and only real plants and real flowers.
