Layer 1 Design

How do you all handle planning the layer 1 aspect of a new greenfield build out (physical placement in the racks, cabling, patch panels, etc.)

Are there any good guides or reference material specifically for physical layout and cabling in the data center environment, or especially for a collocation space?

I was more or less thinking after designing the “logical topology,” i.e. the layer 2/layer 3 connectivity, that the physical layout and cabling would sort of just fall into place. However, I can see many ways to do it, and it could either end up absolutely pristine or a hot mess. Especially since our design foregoes such as “inside/outside switches” in favor of vlan segmentation, which is kind of abstracting the layer 1 choices and making it all a little jumbled.
