I have taken to using a single card in person, and a single card online. The Card on use online is also a Capital One account so I make use of their Eno service to make virtual cards for every vendor

If some company does not want to unsub me, I just turn off that virtual card.

I do the same with privacy.com, along with a unique email via fastmail’s masked email feature.
