I would say level 3 cloaking is more an insurance/damage control against (un)lucky damage from missiles and/or boarders depending on your configuration, especially against flagship.
Small tip that I couldn't find in T-hawk or Sullla writing (afair) is that I found defensive drone to be also quite efficient to gain time versus hacking drone and boarding drones from Flagship where you will obviously need to power and use a def drone anyway, so I will leave it on until hacking/boarding manage to go through (it will at some point, and then I micromanage on/off the def drone).
