George Washington determined that the title of the president should be "Mr. President." He wanted to establish a title that was respectful yet not monarchical, reflecting the democratic principles of the new nation. This choice helped set a precedent for the office and emphasized the role as a servant of the people rather than a figure of royalty.
The title that George Washington and Jefferson Davis shared was being a president.
the congress agreed that Washington should be called "Mr. President" rather than by a title that would suggest he was king.
Mr. President
Mr. President
President

George Washington accepted this title. He did not want to be called "Your Highness" or anything that sounded like a king's title.
The nouns are: George Washington and President, proper nouns for the name of a person and the person's title.
He was much more pompous that Washington and did not like Washington's idea that people should address the President only as Mr. President. He wanted something more lordly. Since he was short and fat, somebody suggested, "His Rotundity" as a fitting title for him.
Washington didn't want an elaborate title like those used with European nobility and royalty. He preferred the more direct Mr. President.
Neither. We say the title and name together: "President George Washington fought in the Revolutionary War", as opposed to "President, George Washington, fought in the Revolutionary War". To make it an appositive it would need to read: " A president, George Washington, fought in the Revolutionay War". Because then it is reiterating "A president" but isnt necessary for completion of the idea.
To pick a title for a book or story, the title should capture the theme of the story. To know what the title should be we would need to read the article or story that is in question to determine the story.
