I. didn’t cover my south facing kitchen window, for pretty much the same reason as you…lots of spaces and I want to be able to get out the Windex... Do an outside motored awning.

IMO solar shades will be needed to control heat and UV rays or all the fabrics will be bleached in no time . I would probably do motorized ones so you can enjoy the cloudy days with no blinds. I see no need for privacy on that huge wall of windows so there I would just do the solars they will allow you to keep the view all the time. BTW the view is better when you choose the darker color like charcoal or bronze. Then on the windows where nighttime privacy is an issue you can mix the blinds with either roman shades or drapes but my choice would be roman shades. The other thing you can do is to make those top windows have permanent solar shades custom made to fit and then use the roller ones just on the bottom.

solar shades with a clip at the bottom they will control the sun and with the clips won't blow in the breeze and bonus you get to keep the view and they are very afforadble I use Steves blinds 10% weave and a dark either charcoal or bronze for the best view.

I would recommend some roman shades. Their are plenty different options for light filtering so I'm sure you could find some that block out enough light for you. You could even get some blackout valances that would fit the small window and provide the light filtering you need.
