I think wood blinds will look nice. I would try to match the windows. The drawback with woods is because the headrail is about 3 inch wide , you will have larger gaps where the blinds will butt. Romans, when drawn up will cover 6 inches or more of your window. My choice would be top down-bottom up cordless cellular shades in an earth tone color. Nice clean look with no cords, small headrail and very energy efficient.

In that window, to make it work for your husband and you and allow you to control the light, I would use wooden blinds that match the trim (and a shade lighter if you can't make it exact) with attractive tapes.

I'd use very light-weight ones, and use the widest slats I could make fit, because it takes fewer of the wider ones per shade, which means that they stack up higher when you pull them all the way up.

If that is appealing to you, from what I can see, you will need to add a header from which to hang them, so that they will clear the windows when open. That can be masked with molding stained to match. Some blinds have valances of molding available to match.
And it also means measuring carefully from side to side, based on the spot at the top where they would hang, because every additional bit of distance out from the window means their width might have to be reduced a bit, so they will clear each other at the inside corners. (Am I making that part clear?)

For the safety of your children, whatever treatment you choose, think about how to corral the cords so they can't get tangled in them.

I still love aluminum mini-blinds, and to my eye would be a fine solution for your windows.

You could also do a roman or roller shade on the flat wall, covering all three windows. When the shade is up, the entire window would be clear. When down, you would no longer see the bay window.
