What do you mean by this? I understand your caution about the change fees (many ppl indeed often interpret the "no change fee" as a "no fare difference to be paid" which is false), but I don't understand it about the refunds. If your ticket is refundable, you are totally reimbursed, aren't you? The only possible fees would be the issuance fees (not refundable, but =0€ if you don't book via AF.fr but AF.xx) or if you need to contact the phone agents (not needed if you buy your ticket online).
OP may keep in mind though that even on a non-refundable ticket, all taxes are refundable if the ticket is not used: on a cheap ticket, that is non-negligible (~ 30% of the cost of a 82€ AMS-CPH o/w ticket).
Whether you should buy the cheapest ticket available or a Flex ticket should be assessed not only though money but also time, risk... and btw seems a bit off-topic.
