Sherry it is a V-I from one movement to the next.
I think there are two questions about the final chord for a person hearing the movement on its own, the final chord as a whole, and why the third an fifth of that chord are what you hear more.
The measure lands on an F major chord, I since the movement is in F, and modulates to a C, the V chord. The C should be held while the F and A go through a little cadence and end up on E and G, making the C major chord.
The next movement is also in F, so it’s a V-I from one movement to the next. In addition, that movement has a C as the pickup note, which could be why the C in the first movements final chord doesn’t get top honors. The change is more dramatic if the last thing you hear is the shift to E and G with the C in the background.
