The Lufthansa website itself is fairly clear about what class on Lufthansa/LH group you book into, regardless of the status of light/classic/flex. Light changes baggage limits and potential rebooking/refunds, classic is rebookable, but not refundable, flex is refundable at a fee. Your status mile earnings stay the same, regardless of the subset of the booking class. Award miles are a function of money paid.
