Use the simulator to investigate strategies, not an actual game you're trying to play.

To blockade, use a strategy set with "don't target types" set to true for Planets, and Seekers Targetted on Self and Seekers Targetted on Others. This will allow your fleet to attack defenses without firing on the planet.

To have ships use individual strategies, use a fleet strategy with ships set to Break Formation - they will then use their own design-specific strategies.

To have a specific ship use a different strategy from the one for its design, put it in its own fleet, with that fleet set to not break formation.
