Poe zigbee coordinator placement

I am thinking I'll do a network run to either a central closet or to the cieling central to my one story house. Does this make sense or should I just throw the coordinator on one of the ports directly in my rack I am new to anything but wifi andy understanfing is that the zigbee devices will chain to each other mesh network style but idk if having the centralized point as the main is the way to go. Thanks for any input.
