> This will likely involve installing some overhead infrastructure and trays that let you route fiber cables from the edge of your cage to each of your racks, and to route cables between racks

Perhaps I am reading this wrong, as you appear to be fiber heavy and do have space on the ladder rack for copper, but if you are commingling the two, be careful. A possible future iteration, would consider a smaller panduit fiberunner setup + a wire rack.

Co-mingling copper and fiber, especially through the large spill-overs works until it doesn't.

Depending on how adaptive you need to be with technology changes, you may run into this in a few years.

4x6 encourages a lot of people putting extra cable up in those runners, and sharing a spout with cat-6, cx-#, PDU serial, etc... will almost always end badly for some chunk of fiber. After those outages it also encourages people to 'upgrade in place'. When you are walking to your cage look at older cages, notice the loops sticking out of the tops of the trays and some switches that look like porcupines because someone caused an outage and old cables are left in place.

Congrats on your new cage.
