Answer 1

Basic principle: heavy from below, light from above. To the very bottom - the UPS, to the very top - an optical cross + organizer, further as the weight and the need for accessibility for convenience. As a rule, they put a switch + patch panel + organizer, and so many times. It is highly desirable to leave space next to all active equipment (UPS, switches, routers) for their prompt replacement. If you make an organizer under small switches, in case of expansion, plug the switch in its place, but this will not work with a UPS, you must foresee it in advance.
Variations are possible depending on the port capacity of the switch, patch panels, multi-pair cross-countries, large multi-unit equipment (20-unit cisco), the presence of telephone cords, the need for fans, medical shelves, etc. It is also convenient to stick one shelf somewhere on top.

Answer 2

IMHO.
If you fit all the equipment in a rack and there is no equipment that emits heat, then ...
Below is the UPS, then the optical cross (it is rarely touched), then the patch panels + switches, at the belt level and above the server for easy replacement and modernization of the insides, chest level is KVM / keyboard + mouse + monitor, at the very top is a router / distribution switch. My height is 1.93, so it's extremely comfortable for me.
