Going back to a minor point for a moment.

I'm not sure "stood by" implies Elrond participated (or assisted) in that last fight with Sauron. The text I I think pretty straight forward with how those events played out.

1. Sauron goes into combat with Gil-galad and Elendil.
2. Gil-galad and Elendil both perish, but Sauron is overthrown in the contest as well.
3. Isildur cuts the ring from Sauron's hand.
4. Elrond and Cirdan were the only others present and counseled Isildur to destroy the ring
5. Isildur claims the Ring as weregild for the death of his father and brother.

"I was the herald of Gil-galad and marched with his host."~The Council of Elrond

I'm not sure if herald's had other meanings, besides being a messenger? All Elrond says is he "marched with his [Gil-galad's] host" and "stood by" him at the end as one of the few there who knew what happened.
