Just a little ceramic information to share as a potter. Vitrified simply means the clay has become glass like by being fired to its proper maturing temperature. Usually ceramic tile means it is a lower temperature clay like earthenware or terra cotta. Porcelain is fired to the highest temperature and is more vitrified if you will. This usually means it is less porous to to absorb water and harder. Low fired ceramics with glazes much darker or lighter than the clay body will show chips easier. Rectified has to do with making the edges precise enough to fit smoothly together for less grout lines. So porcelain cost more to produce but it is more sturdy. All clay tiles should be vitrified.

I second patricia, make it all the same flooring. I did the 'wood floor in the walk in closet' while the rest was tile, ended up taking it out and just tiling everything, the threshold was collecting dust and grime and annoying for my laundry cart.

I'm sure I can do a wooden flooring with that same color pattern and texture . just don't know which one it could be .. not sure if that's wooden flooring in the first place but wooden flooring will look as stunning as this

Well it depends on your wall color as well . since you have such concrete looking floor I would recommend you can chose any electic color like lemon , orange , yellow to give a bright look and uplift room mood or chose any pastle color of your choice for subtle feel . :)
