[MCU] Are the events of the various Marvel movies considered the entirety of the activities of the Avengers, or is it implied that they also foiled various plots and supervillains that we just never saw in movie form?

The Avengers definitely did more stuff than is shown in the films. In age of Ultron they briefly mention that they have searched other hydra compounds for Loki's staff before the one they attack at the start of the film.

The quinjet is leaving the avengers base in the end of Spider-man and in infinity war Captain America's costume has damage. These also strongly suggest the avengers are doing stuff between the films.
