No expert here, but when our daughter had her kitchen re-modeled she had the faucet mounted an inch higher than her tallest pot. Seems to work for her.

I would tile around the window because it's in an alcove. It would be easier with narrower molding or no molding if you're able to tile inside the window frame. Keeping the trim, I'd paint it so it disappears. Also, don't continue the tile around the corner on either side of that wall. If you don't want to tile the entire window, at least bring the tile up to about the height of the hood.

Thanks all for this input. Very helpful. Today I built a fake tv out of Fedex boxes I had at the office and placed it at various heights from 46-54 inches and sitting at the same height and distance as my living room would be. Personally, while my eye level was between 40-43” depending on the seat and my slouch position, I found my eye naturally resting at at between 46-50 inches. My couch, dining chairs and comfy sitting chairs all have a little natural recline to them. I decided to install my electrical outlets and wiring at a position that gives me a range to decide between 46-52 center once I’m ready to mount. This decision seems to vary for a lot of people so I’ll summary why I am doing a mount (even if it’s only a few inches above console) and why that height: I have a few different places to sit/see TV: comfy lounging chairs, my couch, dining table and my open kitchen. Mounting with an arm gives me an opportunity to adjust depending on what’s being used I am using a soundbar and want to make sure the sound field is adjusted as the tv moves so sound travels in the right direction based on which way tv is pointing. My placement allows me to upgrade tv to a bigger size while keeping center the same My soundbar adds an extra 3.5” to bottom of tv so I can mount a little higher if needed while preserving the right space between console and tv I have my eye on a 27” high console I really like. To do that, I need my center of tv to be at 47”ish so that the soundbar can clear the console and float Would like to get sound of the bar closer to ear level versus really low to the ground.

Are the new uppers going to the ceiling? If so, I would tile the whole wall to the ceiling. I think you can mitigate the unbalanced look with art or hanging planter of some sort.
