I found a parquet for the floor last week that is just right in color and texture. It is 22 mm of solid wood in pre-made panels of a dyed beechwood that is pressed to make it harder. I decided on the matte varnish finish, as it is more stain and water resistant than the oiled finish.
Here is a picture of a similar parquet installed that the provider sent me. The color of my choice is a bit lighter.
