The only other caveat is that Galadriel, Elrond, and company are supposed to be the last High Elves sailing West. High Elves are an in-game "race." So, that's a bit tangled, although I noticed how Gandalf's quest-text at the end of the Midsummer Wedding hinted at how they might try to compensate for that, (maybe ret-conning Elrond and Galadriel as "the last of the Truly Great High Elves" or something- that would bend the lore, but the alternatives aren't many; they've cornered themselves on this, *laughs*).
Celeborn & Cirdan depart Middle-Earth sometime in the Fourth Age aboard the Last Ship with Cirdan specifically leaving as no other Elves at that point showed an interest that they would ever leave.
When Celeborn & Cirdan depart, this is the last of the High Elves to depart.
So High Elves being in Middle-Earth through arguably past King Elessar's Passing in Fourth Age 120 will be a thing.
As with King Elessar's passing the last true part of Numenor also passed away and what had made up the Greatest Line of Men had peaked & bloomed once more during King Elessar's Reign so the small Golden Age of Middle-Earth where some hints of all the previous Ages were likely seen began to fade as well.
