I would suggest a "satin" if that isn't available them matte will often match fairly well. Just avoid glossy as it often ends up looking tacky. I prefer to pick my color regardless of finish then spray a matte clear over everything
My thoughts would be to just stick to stock elites. Those are running you .10 a piece. If you keep an eye on Amazon with Prime you can occasionally find the 75 pack of elites on sale for ~$15. AT that point you are paying .20 a pop. Which is worth it IMHO to have to guarantee of quality. But hey, with free shipping, you don't have much to lose picking up a few and seeing how they do!
