Expansion joint in floor tiles in the kitchen?

Hello,

we have decided on light floor tiles for the kitchen and would also like light grout. I know, I know, generally not recommended... I did some research on the topic online and read something interesting about dispersion grout. They are supposed to be color-stable and dirt-repellent because they have a closed surface. Does anyone know what to make of this (application area: kitchen, matte porcelain stoneware tiles 30x60, grout 2mm)? Here are some examples: "Oka Color" from Kiesel codex-X-Care.

Hello,
that would also be a topic for us, as we will have tiles throughout the entire ground floor. Perhaps someone has experience reports regarding stain-resistant grout by now?
Best regards
