Yes, you are burning your bridges with a chargeback which is why you should threaten it to support first and only after they say no do you transfer all your domains, wait a few days, then file the chargeback. You somewhere between 60-90 days to issue a chargeback so OP has plenty of time.

Yeah, I already transferred everything else to Cloudflare in advance of this so that part should be taken care of.

I'd say don't wait, just do the chargeback, if you threaten all they will do is try to stall you out of the chargeback window.
