We have the same laminate in our entry, hallway, kitchen and family room and are putting slate in our sunken living room (which is adjacent the laminate hall) and carpet in our bedrooms. All the bedrooms will have the same carpet. The two bathrooms have different tile. Having each room with different carpet might be a bit disjointed. How about using different painting or decorating techniques to bring individuality into each boys room? i.e. granite or leather look painted walls or wallpaper. I don't think two different types of wood next to one another will look good. Most times people try to match the wood floors - not use different types. If you really want a different look in one of the rooms that will have a wood floor - you can use an area rug to partially cover up the wood floor that looks better in the other rooms - or choose a wood floor that looks good in all the rooms - something more neutral grain. Just my two cents worth.

Lutron makes something like 100 colors of outlets and switch covers. I ALWAYS try to match them to the wall color or accent color if high contrast for visibility's sake is needed. Yes, it costs a bit more than the 29 cent white ones, but it's a detail you see (or don't see!) subconsciously when evaluating a room. Just like having a stark white outlet in the middle of your wood island, sure, you can, but I wouldn't. However, if these are new outlets and you are under the gun to make a decision NOW, then just put in white and replace them later with something from Lutron. I'd also put in the wide rocker switches rather than the small flip ones. But either is easy enough to do at a later time DIY when you aren't under as much time pressure. NEVER pay to have an electrician just change out a switch or switch plate. It's about the easiest DIY imaginable.

If I lived in a warmer climate I would have LVP or Pergo in all the areas except the bedrooms. I have Pergo in my present and last kitchen and it is so easy to care for and as you say indestructible. Next time I am going to look into LVP. I heard and seen too many horror stories about care, maintenance and wear problems of hardwood. Then people cover them up anyway with large area and scatter rugs. Kind of like wearing a expensive awesome dress, but never taking off you coat because you might damage it. Cold area or not I still like a soft warm quite carpet in my bedrooms.

Tile is fashion. Tens of thousands of new choices are discontinued every year and 10,000 new ones are introduced every year. You’re not finding a Alfred Dunner plaid skirt from 1999’s collection, even at TJ Max. You might find it at Goodwill, if you had a network that connected all of the Goodwill’s in the country, and they cataloged their donations to a database. That no more exists than does a database of old discontinued tile. You can’t find replacement tiles for tiles discontinued in 2018, much less 2000. Not unless it was widely used by a tract builder, in a tract neighborhood, and every house comes with a box in the attic. It’s the worse kind of needle in the haystack. Because the haystack is 20 years old. Everything done in 2000 is now 20 years old. Time to assess what has stood that test of time, and what wasn’t a durable or attractive option, and needs to be redone with something else.
