Then I added in the Freiza Saga with the Saiyan Saga. I was referencing when he blew up Namek. In the Cell Saga, I felt it was more to motivate his son. Either way, he still failed to kill Cell while he was alive. But he does still embody this idea even in the Saiyam saga. He didn't really "die" but was rendered paralyzed for the last part of the fight due to his spirit bomb. He couldn't do it himself thus had to give it to Krillian. After which, he was able to coordinate the final moments of the Saiyan saga telepathically. He didn't sacrifice himself that time, but his role as the "sole savior" if you will. He probably could have pushed himself, as it would be within his character, but he chose not to.

Frieza blew up Namek, not Goku, in case that was what you were implying. Goku also didn't intend to die in Cell Saga, not even Goku knew that it wouldn't see Cell destroyed once and for all. He did fail to kill Cell by himself, as you said.

The issue with Goku is that he wanted to stop being the one everyone had to count on to win, he wanted to let someone else have the role so he didn't have to be wished back time and time again. Gohan was entrusted with the role and A WILD BUU SAGA APPEARED! TORIYAMA USED 'GOKU MUST DO EVERYTHING!'. ITS SUPER EFFECTIVE!
