If your speed is set at zero or if, due to effects, your speed is reduced to zero prior to you executing a maneuver, do you nonetheless have a "maneuver" that triggers Fighter Coordination Team? Thanks!

Yes, it's a speed zero maneuver.

Thanks yes - I just had to keep reading. Found the answer in the rules reference:

If a ship executes a 0-speed maneuver, it does not move
from its current position, but it is still considered to have
executed a maneuver.
