I was thinking that because the Trubridge lights are so beautiful, a simple LED pendant light would be best as they do the job without taking away from the beautiful light!

Beautiful clean modern kitchen! You have a great opportunity to put your personal stamp on the space with a unique backsplash. As you've heard already there are some different approaches. I'd probably place the backsplash up to the wall cabinets and up to the base of the hood. Then continue the backsplash at the same height (18"?) behind the sink. Then place an inspiring colorful picture above the sink to break up the wall. Here's a picture with pendants that aren't too obtrusive. Having multiple levels of lighting at different lumens makes a more inviting feel to the space. I couldn't decipher your flooring, but you may also want to consider adding some nature elements like a type of wood flooring, wood stools, etc. Good luck!

Wall sconces are for additional lighting mostly decorative you need ambient light, task light and decorative light in a space the downlights are the best way to get ambient light which the allover light you need then lamps for reading or any task that requires good close lighting and then your sconces

Sorry, don't think it fits, The prongs on the light give it a more circular shape but you have this over a beautiful oblong bench. Always rectangular or oblong over rectangular. And the dark ends of the bulbs will create shadows, not so good in a work space. Used to work in lighting for a few years and it always comes down to what makes you happy. I would have tried to steer you in a different direction, Hope this helps.
