Canon of Dragon ball?

Hello, friends, what is the canon of Dragon Ball? Let me explain:

I had a couple of questions about the canon of Dragon Ball.

I have to say that I am reading the manga and I am on the Cell saga, so I am not very new to Dragon Ball.

I assumed that the canon was Jaco the Galactic Patrolman, Dragon Ball (the original manga + Z) and the Super manga.

But as far as I know, the Super manga does not involve the movies.

And here comes my question: do the movies have a manga? Because as far as I know the movies are canon, but I was hoping they would have a manga, although I think that is not the case, I was asking to see if someone could answer my question.

Even so, I do not take the canon of Dragon Ball at 100% because there are many nonsense and plot holes.
