My preferred way of dealing with the 32nd century remains Star Trek: Left Behind.
Elder races in the Trekverse never seem to stick around for long. They die out or become some sort of non-coporeal beings. So just have the majority of the Federation population ascend to a higher plane of existence and leave a number of weird magic-tech artifacts the survivors can barely fathom.
