From your picture it looks like the lower windows by the fireplace are about the same height as your side windows. Could you put the same curtains/shades/drapes on these windows and put a blind on the top windows by the fireplace. IMHO the curtains should be all the same in one room.

The wood blinds are what we did. I would think about what kind of light and/or privacy control you may want -- and that can vary depending on the season. I get sun coming in at such a low angle in the winter that it can be the most annoying light problem we have. Blinds allow you semi-privacy when open and can be adjusted for some light control with a view. Because they are heavier, it is not suggested to leave them up for extended periods. I had in the past, but with the long windows in my FR, these are heavier than what I'e had in the past and the guy we bought them from said open, don't raise them for light and view. Raise them for cleaning and put them back down. Shades vary by type, but tend to give you filtered light or no light on the portion they block. The top down shades there now do look nice -- like an internally hung tailored valance, but they block light and trees from the top but allows you to see the table and anyone sitting at it or what is going on in the yard even if seated. If you leave them mostly open and get enough light, they may be fine. If you would rather see the trees and sky and screen the furniture, you light like a bottom up version. Most of those also give you the option of raising them and going top down. That is what I plan to put in my MBR.

This makes me chuckle IMO the room that needs privacy is the bedroom and unless you run around naked in the rest of the house you could just do solar shades to control heat and light they allow you to keep the view and give you privacy during the day and if you think you need privacy at night hang some nice drapes with grommets that open and close easily .I trully think most people are not into in looking into other peoples windows as much as you imagine.
