Safari supports content blockers, which are basically lists of content to block. AFAIK, there's also a limit (50K, IIRC?) to the number of rules that can be bundled within one extension. With the popular lists used with an extension like uBlock Origin, 50K is quite a small number. So multiple extensions would be required to get close to uBlock Origin, even if we dismiss element blocking rules and other features that uBlock Origin offers.
