Hi, I'm helping my mom decorate her new house with a coastal theme, but don't know what to do for these windows and was hoping to get some advice. The house has an open living/dining area with basically 4 big windows, all different, sizes, shapes, and placements. Photos are attached (ignore the staged furniture).

How can I treat these different windows without it feeling mismatched or like there's too much window treatment within the room? Would it look weird to put curtains over the glass sliding doors and then have nice blinds covering the other windows? Or should they all have just blinds? Or something else? (My mom doesn't like shades, so those aren't an option.)

In the photos below, you can see there's the full height glass sliding doors. And then there are 3 different mid height windows: 1 in the far left corner, the window to the right of the glass doors wraps around the corner, and then there's one in the dining area. The room faces south, so we need to have something covering all the windows to block the sun.
