I’ll +1 the Signum recommendation combined with Velcro tape/strips. Get your cables routed together loosely, then use Velcro to hold the loose bundles across the floor. Once you get to the desk, use one or two Velcro strips screwed or taped at top and bottom, kept loose, to hold the vertical cables. Once in the signum, loop once, pick a spot to leave excess, then make the end run. Once done, take the excess and wrap once or twice, velcroing to the bottom of the signum in the center/out of the way. I mount my power strips to the bottom of the signum as well.
