From what I hear about Akira Toriyama, he comes off by someone who does whatever his boss tells him to do.
Could have ended after the
Pilaf Saga. Basic journey.
Piccolo Saga. Goku is the strongest person on Earth. Implied to succeed Kami.
Frieza Saga. Goku became the strongest person in the universe. Died fighting on an exploding planet.
Cell Saga. Gohan surpasses Goku, most of their friends, and their strongest enemies combined.
Buu Saga. Goku returns from the dead and helps defeat a Godkiller.
Shadow Dragons Saga. Goku and Shenron leave for 100 years. The reappearance of Shenron is accompanied by the reappearance of Son Goku.
Dragon Ball Online. Goku and Vegeta in their old age fight one last battle in an uninhabited section of the universe.
Dragon Ball Super should have taken place in one of two eras.
After End of Z. Goku still misses Bulma's birthday party due to training Uub. Beerus still crashes the party looking for SSJG. Nothing really has to change.
After GT, post-100 year time skip. Beerus appears before Goku Jr and Vegeta Jr inquiring about SSJG. The closest they can think of is Goku, but he's dead so they wish Shenron will help. The rest goes down just as BoG except with mostly new characters.
I just view all forms of Dragon Ball as different universes. Most simple categorization is
Original manga run
Original anime run including filler, films, OVA, and GT
Anything from previous works that contradict the timeline as well as other media like licensed games and Dragon Ball Super
