If you can paint the kitchen walls and trim the same color, then the trim will look like an extension of the walls. If that is the case, I don't think you need to worry about the stained trim elsewhere.

That might work I would discourage the chaise on the sectional just do an ottoman same sitting comfort but much nicer seating when you company. IMO thi s is ahuge space that is poorly laid out the DR table needs to be about 3x the size I would put it infront of the patio doors off the kitchen then you would have a huge LR with a couple of seating arragements one in front of the fireplace and one for T.V viewing all pieces that can be moved when you have a crowd.We have a large LR and I puposely bought piecs that could be rearranged for different looks and purposes like the Christmas tree for instance .So I have 2 sofas, a chairs that do not match the sofa or each other but work in the space a long bench that can be moved easily wherever I need it I really dislike sectionals because they are so site specific and in your space I think if possible think many useful pieces that can move easily .

I like a lot of light as well. I think everything is well lit except for your family room. Definitely not enough light in there (especially if you want the option of a brightly lit space. There is no center lighting and everything has been arrange around the edges of the room. IMO, what you have is a HUGE span with zero lighting which is not at all adequate. Some people prefer room edge lighting and that’s what they’ll recommend. But if you like a lot of light, I don’t think the way your designer set things up will satisfy that need. If it was my home, even though the ceilings are only 8 feet, I would want a center fixture (small chandelier or semi flush)...something pretty. If you are not sure about your furniture placement they can always install the box with lots of extra wire looped in the ceiling so you can adjust it later. Just take pics of your ceiling joists when it’s all opened up (if it is opened up) so you know where everything is located. Makes it easier later. You’ll have a little sheetrock repair, but completely manageable. I would add more cans/wafers around the center of the room and put them on a dimmer. You can always turn them off or dim them if it’s too much light, but if there’s nothing there, you’re stuck with a dark room and no real way to fix it (other than having your electrician return and hack up your ceiling). I’m not a fan of LED, but some people love it. Just make sure you like the type of light they put out before you bite the bullet on them.

I would do my best to get an idea of how your furniture will be arranged in the room and place the outlets UNDER where the furniture will be (so outlets will be out of sight). There is really no need to have them out in the open as you will normally be plugging a lamp in and not need to access the outlet again. Under the furniture (centering under a sofa or chair) keeps the ugly wires out of sight for a much cleaner/neater look (you wont see the plug sticking up out of the outlet when hidden under furniture). You can also hide extension cords under a sofa and plug a lamp into that, which actually makes plugging in multiple items easy to access.
