Am I misunderstanding this or are you?
My take is the OP is contemplating booking a cheap eco light ticket on AF/KL stock. DL operated flights will book into main cabin. His alternative is to book BE on DL.
There won't be C+ or F upgrades at all when he goes the second route. That is, it is better to have the chance of selecting seats at the time of booking and a shot at C+/F upgrade on the day of departure rather than not having those chances at all.
