One of the 5 windows in my office has its right drape panel a bit behind a secretary desk in here. It doesn't bother me, but you may feel otherwise. My roller shades block the sun and gives me total privacy if I choose to close them at night. My shades cover the full glass part of my windows, but not the outside trim. My windows are standard double hung, and yours appear to be sliding windows. If you do get shades, no matter what material type, and close them at night (just an assumption on my part) wouldn't you need to raise them in order to open the window if you choose to? Would that bug you at all? I may be prejudiced toward drapes, as I make them myself and love fabrics, so change them more often than others might. Here is a pic that I found online with a window similar to yours that may help you decide.

We have a master with a lake view and although it might be a bit more than your budget, we have a blackout cellular cordless shade with motorized lift. It goes across a window similar in span to the three panes on the left side of your photo. It has a remote control and it is a fun thing for us to press a button to behold the morning view from the bed before getting up. We have non-motorized cellular shades on our smaller windows.

Is there any way you can post some pictures for a visual? :)

You can do the panels On the slider which can be pulled aside (they can on windows too) for unibstructed view when opened. It’s also acceptable to shutter the windows with panels and then just place panels on slider. I would do three full panels testing the two windows as one large one. Have them shuttered that way as well so it’s not as choppy. The space between the slider and window i would do one double panelto dress both sides. Or you can do a natural woven shade or roman shade on double windows that pulls up and down. Neither of these will give you view unless opened all the way. Maybe if we saw more of the room we could tell you which would best suit the space.
