I did some more digging on the 21 gun salute. The ONLY gun salute that Biden got is specifically for a visit by a FOREIGN DIGNITARY to the Tomb of the Unknown Soldier at Arlington.

Here is an article saying the 21 gun salute at Arlington was to mark Biden's inauguration.
He did not get one before this or after this. It was with 3 guns at 10 second intervals which, at Arlington, is SPECIFICALLY for a foreign dignitary visiting the Tomb of the Unknown Soldier.
The number of cannon used in a battery depends upon the intervals between each round fired. This includes, for example, a three-gun battery firing two of its guns with five-second intervals between rounds and one gun remaining at the ready in case of a misfire; such a battery would be used at an Armed Forces Full Honors Funeral, or for State Arrival Ceremony of a foreign dignitary at the Tomb of the Unknowns in Arlington National Cemetery.
The wiki is wrong about the interval with 3 guns. It is 10 seconds, not 5 seconds.
Here’s the same 21 gun salute with 3 guns at 10 second intervals given when the Defense Secretary of Jordan visited Arlington.
Today, a 21-gun salute is rendered on the arrival and departure of the President of the United States.
The one earlier on inauguration day is for Trump's departure that morning, NOT for Biden who was not President yet.
