Firefox Focus is available on App Store. You don't have to use it (I don't), but set it as a content blocker in Safari settings.

The only other extension I’ve started using recently, when the quantity/frequency of YouTube ads on Safari became unbearable, is 1Blocker. It includes a specific filter for blocking YouTube ads, and you can use one active filter for free without subscription.
