Vanguard was about the set-up got Genesis, the advanced med tech seen in later series, the establishment of Nimbus III, the background of Gorkon among others.
No. Star Trek: Vanguard
was about institutional corruption, guilt, sin, redemption, forgiveness, heritage, oppression, espionage, inter-cultural conflict, the subjective nature of aggression, the forging of community in spite of hinderance, and the nature of the national security state.
It happened to feature
the set-up for Project Genesis and the origins of 24th Century technology, but those elements were minor and can hardly be said to have dominated the narrative.
