Event Names

For all types of interaction, there’s InteractEvent. If you want all block interactions, see InteractBlockEvent and for entities, InteractEntityEvent.
Because these events are not player specific, you have to see what caused the event to fire in the first place.
If you’re only interested in player-caused events, do something like this:

@Listener
public void onInteractBlock(InteractBlockEvent event) {
    Optional<Player> optPlayer = event.getCause().first(Player.class);
    if (!optPlayer.isPresent()) {
        return; // Don't care about non-player caused events
    }
    Player player = optPlayer.get();
    // Do something here
}
