There are some options in the strategy setup screen that you can tinker with. Specifically there is an option to damage until all weapons are gone; also there is a damage percent that you can adjust. Using this, your targeting priority and your "don't fire on types" you should be able to do what you want.

Some "gotchas"

- Missile ships can easily accidentally glass a planet. They have a high damage per salvo and when they attempt to stop damaging a target per their strategy, there are usually missiles in flight which will continue on to further damage or destroy the target.

- Having too much beam weapon firepower in a fleet can result in a similar problem as above.

- A planet is considered to have weapons when it has undestroyed weapon platforms.

- If you capture a planet with enemy satellites, moons (with weapon platforms) or defense bases in orbit, these will attack your newly captured planet. Try to take these out first. Although targeting a main planet instead of its moon really doesn't work; your fleet will attack all planets in the order they encounter them on the combat map and capture the closest one(s) first and then continue to capture up to the number of troop transports you have in the fleet.
