On the other hand, if CX cancels or there is a significant delay, OP will become eligible for a full refund of the ticket to his original form of payment.

Thus, notifying CX is at best of no advantage to OP and at worst, may cost him a refund.

Don't worry about CX. It has calculated the percentage of passengers likely to no show and will overbook to deal with that (should loads even come close to requiring that).

Just wait till the day before-ish to cancel, if the flight is operating.

There simply is no reason for a passenger to risk his funds to "help" CX when CX calculates no shows into its RM/IM algorithms and overbooks to deal with the issue (to the extent that the flight is even full now).
