Your objection to flatness is wrong. During inflation the cosmic horizon scale was a million billion times smaller than a proton. That transitioned into the large scale of today. This can still happen in a flat infinite spacetime.
Inflation involves the vacuum transition to a small value in a bounded region in the de Sitter manifold of inflation. Hence flatness. If there observable universe is an expanding 3-sphere there is more to this than current phenomenology.
