Ok...first things first. Janka hardness ratings only apply to solid hardwood. Engineered planks do not work with Janka because the plied layers underneath are often 'soft woods'. Considering Janka measures how much force it takes to imbed a metal ball into the wood, it isn't possible to offer Janka scores for engineered. They just don't compute. The next thing I'm going to point out is the oddity of trying to match the ENTIRE HOUSE to a single room of existing hardwood. You have a small amount of hardwood that is dictating the rest of the house. It's not impossible but it is HIGHLY unusual. In other words, you are trying to put down more than a thousand square feet of flooring by trying to match 150 - 250sf of dining room (I don't know the size of your dining room so I'm only guessing here). That's a little like putting the cart before the horse. Usually we see this the other way around. Usually we have a house full of hardwood (big amount) but the bedrooms have carpet (small amount). The homeowners then agonize over getting a match for the smaller area. That is normal. As for your price range that you are looking at, they are too low and a little thin. The gold standard is 3/4" thickness (solid or engineered). An engineered product with 3mm or more of wear layer is the base level. The thicker the wear layer the more times a floor can be refinished. The Gold standard is 6mm wear layer (usually in the $10/sf range). If you are having a hard time finding floors that you like, you might want to think about replacing the dining room at the same time. This takes away all the pressure to work with low-grade hardwoods just to get a match to a small amount of hardwood. Solid or engineered should be more than what you are looking at for price. Prefinished wood flooring should be in the $7/sf just to start and they go up from there.

That is on the higher end of parquet floors, have you considered other options like SPC? You can find SPCs for a much lower rate and similar visuals, if cost is a big deciding factor. There's also engineered white oak styles online for only $6 a sf. You can compare specs & warranty to what the Mirage offers to get a good idea. I've dealt with this brand before, but haven't installed Mirage.

@tdld This is the online store I've used to get my Haro - https://shop.anchorfloorandsupply.com/ They say 5 samples free but I've gotten a few more on occasion due to some indecisive homeowners lol. you can try their room visualizer too if you wanna play around with some ideas.

Do a sand on site hardwood ( White OAK /select ) board width you select, and stain/finish on site to your liking. If you want a pre finished, selection, you need to go shopping, look at the wear layers on any you select. Bring the samples home. this is a LOCAL, endeavor. Personally? I'd paint the built in. Feel like and awful lot of wood : ) Pre finished IS hardwood, so is engineered flooring with a different substrate. ........sand on site hardwood is forever......and will outlive you. Depends of course, WHAT is beneath your carpet. If a slab/crawl space foundation? You need engineered product, and a moisture barrier.
