The thread title drew me in but I wasn't expecting the OP to focus so closely on species-based lore and differences. On that front I agree with the OP in that I too am happy to stick with just the Tolkein basics as far as PC-playable species goes, and while the species have their own lore in my setting it's almost never relevant in play (other than divine stuff, see below).
Instead, IME the lore "really matters to the players" in two very common instances:
--- players who wish to play Clerics or Paladins (or similar) need to interact with the setting lore in order to decide on their deity or pantheon and then roleplay their worship of that deity; ditto perhaps for classes or characters that come with a Patron of some sort. This one's pretty obvious.
--- when the lore directly informs the current story, adventure, mission, or what-have-you and the players in-character thus need to research into that lore. Usually, this means looking into the in-setting history of how and why things got to the point they're at now in order to provide a better or clearer idea of what best to do next, and can be on a micro or macro scale. Sometimes instead it means looking into the lore in order to (try to) assess what future effects their current actions might produce.
The only other time setting lore tends to rear its head is in fits and starts during downtime activities, when the PCs interact with elements of the non-adventuring population and-or places in the setting.
