[Raynor]

The entire people of the Vanyar (presumably only the male elves though), led by Ingwe.

Of Ingwe it is stated in The coming of the elves that he never returned to M-E.

The Noldor of Tirion led by Finarfin
...
The Teleri transported the Host but refused to set foot on Middle-earth, remembering the burning of their ships at Losgar

True enough

But the host of the Valar prepared for battle; and beneath their white banners marched the Vanyar, the people of Ingwe, and those also of the Noldor who never departed from Valinor, whose leader was Finarfin the son of Finwe. Few of the Teleri were willing to go forth to war, for they remembered the slaying at the Swan-haven, and the rape of their ships; but they hearkened to Elwing, who was the daughter of Dior Eluchil and come of their own kindred, and they sent mariners enough to sail the ships that bore the host of Valinor east over the sea. Yet they stayed aboard their vessels, and none of them set foot upon the Hither Lands.

The Three Houses of the Edain, what was left of them anyway, led by Elrond and Elros.

IIRC, the twins were born in 528 FA, while Earendil reached Aman in 536; I suppose the war starter few years after, which is no time for Elros and Elrond to grow to be leaders of armies.

There is a similar statement in Myths Transformed:

He, like Melkor, practically never is seen or heard of outside or far away from his own halls and permanent residence. Why is this? For no very profound reason. The Government is always in Whitehall. King Arthur is usually in Camelot or Caerleon and news and adventures come there and arise there. The 'Elder King' is obviously not going to be finally defeated or destroyed at least not before some ultimate 'Ragnarok' – which even for us is still in the future, so he can have no real 'adventures'. But if you keep him at home, the issue of any particular event (since it cannot then result in a final 'checkmate') can remain in literary suspense. Even to the final war against Morgoth it is Fionwe son of Manwe who leads out the power of the Valar. When we move out Manwe it will be the last battle, and the end of the World (or of 'Arda Marred') as the Eldar would say.

[I would note that Manwe would have particpated in previous wars, and that Fionwe is mentioned as his son, an idea which he seemed to have discarded later.]
