If the fleet's strategy is set to break formation (which it almost always should be), then the fleet's strategy doesn't actually matter. To capture planets, the ship carrying the troops must have Drop Troops as its primary movement strategy (which is how the Capture Planet strategy is set up by default). If any friendly ship with troops on board and a Drop Troops strategy is present, all friendly ships will automatically only attack planets that have armed weapon platforms and will stop once the last armed platform is destroyed, at which point the troop ship will stop following its secondary strategy (usually Don't Get Hurt) and approach. If the troop ship is the only ship present, then it will charge the planet in an attempt to drop troops before the weapon platforms can destroy it.
