I use Privacy.com to make virtual cards for this purpose.
I think Apple's credit card does something close to this:https://www.idownloadblog.com/2019/04/01/apple-card-virtual-...
Privacy.com offers an easy way to spin up virtual cards. Keep in mind your bank (and cc processor, and/or the merchant) probably sells your transaction history, etc. to Google and other big data perverts.
privacy.com lets you create virtual credit cards so you can block these from happening at where they charge you
If you're concerned about fraudulent transactions, you could use single-use virtual cards offered by banks like Revolut (or equivalent in the US).
My bank offers virtual cards. Can generate and disable them in the mobile banking app, no need to go to the physical bank for it. I have a card for each service I pay for. Also useful for "free" trails that wants you to enter a CC. Oh and the the whole virtual card feature is free from my bank, no extra card fees etc. (I'm not in the USA)
Revolut offers this. I can create virtual cards and one-time-use cards.
If these things bother you, consider a service that offers virtual credit cards. Privacy.com or Revolut.
Just use privacy.com virtual cards as an interface to a real card. When you want to unsubscribe just close the virtual card to said service.
privacy.com lets you create a unique credit card # for every retailer for free. You can put transaction limits on them too.
