Break this down into two steps to make it easier. Tackle function first. Don't worry about a valance until after you live with the shade for a while. Get dressed and go to the stores and play with their displays. Find one that give you privacy, but also works with your fan. The valance is just fluff and you might decide that with your clean lines that you don't want one. The pleated shades that Daisy mentioned sounds just like what you need. Even a nice tailored pulldown sounds great with your Shaker-style furniture.

I would 100% recommend going with poly-resin shutters. They're perfect in bathrooms as they are waterproof and durable. Shutters also create a beautiful curb appeal. Here is a picture of one of our bathroom projects. We have plenty of information about design options etc on our website, depending on if you want a modern look or a more traditional style. Shutters are so versatile and you can create a look to match your style.

Sorry I disappeared. Regarding the main objectives: Our location is SoCal, and a majority of our windows face the South. So a lot of sunlight. Blocking the direct light falling in house is important, but we don't want to cut it out completely making the house dark (for the living room, kitchen and other common areas), And in the bedrooms we do want the blackout. The house is not fully furnished yet as we moved from a small apartment to this place, and that project is a separate work in progress. But from a general preference standpoint, we like the Earth Tones in colors, simple clean lines with the styles, and natural wood options as much as we can. In the kitchen almost everything is stainless color. And currently the flooring is a combination of dark brown and grey, and the carpet is tan. But we want to change the flooring to a lighter brown+grey type of LVP when the budget permits. So, any window treatment that is kind of neutral and can work with the current flooring as well as future changes would be great. Not sure if it is possible to give any ideas based on this info. And I know it is difficult without the real pictures.

If privacy is important, I would get cordless inside-mount honeycomb shade because when they are up they take up very little space. You have a fabulous view, a roman shade will partially block the upper portions of your view, which to me are the nicest areas to look at. My second choice would be cafe curtains to hide the street and driveway, while making the most of the upper portions of the view. Solar shades are nice too, but will provide very little privacy at night.
