close range is your best option, samus cant spam her projectiles and her anoyning Zair, her close range is good, but lacks in priority and strenght.question about that match up. In that situation would it be better to try and apply close range pressure to Samus or jsut try to out camp them. I would probably try to be aggressive.
think in it, She dont have a good kill power, for that reason she will abuse of her missiles and Zair to do damage an keep fresh her kill moves
in stages like FD she have adventages because the flat of the stage, we don have platforms and she can spam her projectiles faster than Link, but with close range combat you have oportunity
