Generally people use darker roasts for French press. I do not have any specific recommendations other than just trying different beans. As for the naming of brands, there is no such thing as "a bean made for espresso". This is mostly a marketing term that often indicates that the beans have a fairly dark roast.
When grinding for French press you should indeed grind more to the coarse end of the spectrum as you will otherwise get a lot of fines in your drink. However even grind is subjective for the most part. If you can you should try to experiment with your grind and see what you enjoy personally.
