I am not entirely clear if engineered hardwood flooring is actually made from the specific type of wood listed on the title. Let's assume it is, although you can probably verify this by getting details from the manufacturer. Your first option seems to be white birch with a cherry finish, I guess that is the meaning of what you called it. The second option is male with a Messina finish, I assume it is a Messina finish, although I don't know what that is.
So let's get to the hardness issue. There are two hardnesses that are of interest. The first is the finish, since that is what will get scratched initially. I have no idea what type of finish is used on engineered hardwood, but you may want to check with the manufacturer if it is polyurethane, oil or water based, catalyzed varnish, or something else. My hardwood floors are treated with polyurethane, reasonably hard, but certainly subject to abrasion and scratching.
The underlying wood hardness is measured on the Janka scale. The bigger the number, the harder the wood. You can go to the following website for a complete description of the hardness of most commonly used wood species

Note that neither of the woods selected are particularly hard, the white birch is probably paper birch (betula papyrifera), with a Janka hardness of 910, although it could be sweet birch (don't know the Latin name) with a Janka hardness of 1470. The maple could be any of a variety of different species, the best case would be sugar maple with a hardness of 1450, the worst case would be soft maple at 950. The only possible way you are going to know the hardness of the underlying wood is if the manufacturer accurately identifies either the hardness on the Janka scale, or gives you an unambiguous definition of the species they use, preferably using the official Latin name, since the hardness of the two woods you have selected is all over the place based on actual species.
