The Incoterm decides who arranges and bears the main carriage; the freight term is how that shows up on the transport document. Under the C-terms — CFR, CIF, CPT, CIP — the seller contracts the main carriage, so the bill normally reads prepaid. Under the F-terms — FCA, FAS, FOB — the buyer contracts it, so it normally reads collect. If your bill of lading and your sales contract disagree, one of the two is wrong, and it is cheaper to find out before the vessel sails.
