I maxed out my squadron stuff because that also levelled up my rank with the grand company, and gave me access to new items through the command missions... But levelling trust NPCs does nothing but let them into more dungeons so you can keep levelling the Trust NPCs. It's too much of a closed system.
Their purpose is to help you level your jobs without waiting on a queue and to help you learn how to tank and heal without inconveniencing others. They also have a purpose for getting glamour gear without having competition.

Depending on your luck it could be a lot faster to level 3 of them to 80 and farm a dungeon for a DPS glamour item than it would be to enter the dungeon and risk rolling against someone each time, long queue included.
