When you take "one of the following actions"? An Action (Main/Bonus/Reaction) is different from an action (Dash/Disengage/Hide). Conflating these words is an oversight of the designers. The glossary defines the qualities of the actions. The Cunning Action ability defines when they can be taken.
> When you take a Bonus Action or Reaction to attack, you aren't taking Attack action unless noted otherwise.
Do you have an official source or SAC link that says this exactly? I'd like to read more. The provided link does not state that, this is an inference, an interpretation.
Various class features, spells, and other abilities let you take an additional action on your turn called a Bonus Action. The Cunning Action feature, for example, allows a Rogue to take a Bonus Action. You can take a Bonus Action only when a special ability, a spell, or another feature of the game states that you can do something as a Bonus Action. You otherwise don’t have a Bonus Action to take.
Emphasis added.
Reactions are less explicit, but it is almost the same. Everyone has access to the Opportunity Attack Reaction and the Reaction from the Ready Action.
Action lists the standard actions available to all characters. Anything in that list is not available as a Bonus Action or a Reaction unless a feature says it is. It is all in the Actions section of Playing the Game.
