Important considerations when designing telecommunications distribution within modular furniture include all of the following EXCEPT:

Connecting modular furniture pathways to horizontal building pathways is a fundamental design requirement to maintain end-to-end cabling continuity from the telecommunications room to the work area.

Separation of telecommunications cabling from electrical power wiring is required to prevent electromagnetic interference and comply with applicable electrical and cabling codes.

Cable diameter determines pathway cross-sectional fill capacity and minimum bend radius requirements, both of which are critical inputs for modular furniture pathway design.

The concept of derating the fill ratio because of corners is a conduit design principle derived from NEC conduit fill calculations, not a recognized design consideration for modular furniture pathways. ANSI/TIA-569 specifies a 40% initial fill ratio for modular furniture raceways applied uniformly, without corner-based derating, making this choice the exception.
