そして only claims the next thing belongs with the last one, so between two clauses it links states as readily as events (安い。そして、うまい); それから between two CLAUSES recruits temporal order, so forcing it between two simultaneous facts asserts a sequence that isn't there — order-free それから survives only in item lists (コーヒー、それからケーキ).
The て-form is a MORPHEME welded onto the verb — it chains clauses inside one sentence and leaves tense to the final verb, so it can never open a sentence; そして is a free word standing before the clause, which is why it starts a new sentence where て only extends one.
そして only claims the next thing belongs with the last, so it will link two events in sequence (東京に行った。そして、大阪にも寄った); それに adds a further GROUND pulling the same way as the last point, so it misfires on a bare sequence, and 安い。それに、まずい fails outright because the second point pulls the other way.
