Industry standard Cat5e cabling
The big problem with this is that in wall cabling isnt designed to be flexed repeatedly.  It's more rigid to help running it through the walls.  It will eventually break from being moved around too much.  And when it breaks, it will be hard to repair.

Patch cables are usually made of stranded wire and designed to be more flexible.  They are also cheap and easy to replace when they break.

Brands dont matter much as long as they are reputable and of decent quality.  Typically you go from a punch panel in the network room to a wall faceplate in each office.
