You have some good replies here, but I’ll add one piece. You’ve imagined a world where your primary characters are Good. No killing, just defensive armaments, all about diplomacy and exploration.

Consider, though, that interesting stories have conflict. Conflict needs to have consequences to the characters you’re following, or it’s not very interesting.

You’re describing a world that would probably be better to live in than that of Star Trek. But I’m not sure it would result in better stories.
