Now that 10G over copper Cat6a (802.3an 10GBASE-T) has been finalized there aren't any good reason to go with fiber except for physical requirements like Ian stated. Also Desktop fiber aggregation is much more expensive in terms of line cards, diversity of switch choices, lack of desktop NICs. Usually I hear FTTD being done to "future proof" the wiring. Most of the times the fiber never ends up being used. Cat6a is backwards compatible with 5e, so if you are doing a new wiring plant, that's enough "future proof" for the next reasonable term.
