I'd want the light switch to be at the "standard switch height" for your house. That way there is no searching the wall for the switch in the darkness. Or out of habit. I'd not want the towel hanging on the ring/bar to cover anything up. Nor would I want the wire from whatever is plugged into the outlet to be in the way of any switch or to get tangled with the towel. Will things be permanently plugged into it? Or will it be "time of use" only? That can make a difference. With the Thermostat most likely being the least used and if it can't be set at the same height as the light switch, I'd set that a bit higher up on the wall than the light switch/fan switch combo, but aligned vertically with it. Personally, I prefer fan/light combo timer switches. A single switch controls both. You turn the switch on, the light and the fan come on. You turn the switch off, the light turns off immediately but the fan runs for an additional preset time. If you did that, you could put your fan/light switch and outlet in a dual gang box at the appropriate switch height. Put the thermostat in its own single-gang box a little higher on the wall, but aligned vertically with the switch box. Below that, at a height high enough to keep your draped hand towels off the countertop (if I understand your situation I think it's hand towels), but low enough to deconflict with the outlet, place the towel bar/ring. I'd use painters tape and mock up the locations and see how they work. Unless I'm really misunderstanding your description, I don't think "how they look" will be an issue. "New things" sometimes look weird to the un-used to it eyeball. Once you get used to the look, all will be well. So prioritize substance or functionality over style.

I would center them with the vanity @ 11"

Any reason in particular why you are keeping the tv over the fireplace? That must be over 8' high. That's some serious neck strain. I would probably recommend a similar layout to the previous owner. It has lots of seating, divides the entry from the living area. The window looks fine with current shutters. If you do not have furniture, start with the rug first. Find one large enough for the room. Use the colors in the rug to guide you for picking out furniture. Artwork and other wall decor can come later once you have the basics. You could always put the tv on a stand to the left of the fireplace. Have fun.

Thanks for your response. I agree to skip the under cabinet lights. I think I’ve decided to do 1 light over the shelf to the right of the stove, a light to the left of the sink and a light at the same height to the right of the sink. How does that sound? Alternately I could do a total of 5 lights - 2 to the right of the stove, 2 to the left of the sink, 1 to the right of the sink. I had a designer and an architect do drawings. The architect put the stove in the corner which I hated. I have a vintage Chambers stove that is 37.5” wide. There is literally no where else to put it. We have been through tens of iterations. We are going to do a ceiling vent (again I know it’s not ideal. I’ve read all about it but it’s what we have to do). If I put the stove on the wall where the sink is now it pushes the kitchen too far down into the dining area. If I put it where the refrigerator is I have to put the fridge down into the dining area - which I also don’t want to do. Why wouldn’t I be able to open the window? I was planning on doing a casement window over the stove so it can easily be opened. Here’s a pic of the kitchen now that it’s been demoed. We removed the wall between kitchen and dining room.
