Not really. Firefox Focus is free and does a great job. Nomorobo is a call filtering service and it's $20/year, and it also does a great job of blocking ads & other objects.
ka-block does a good job and it's free.
You can turn JS off, which is quite similar to allowing no scripts, but more pragmatically, 1Blocker is remarkable, give it a look as one part of a phone-wide strategy. [Note: from sibling comments, you hate 1Blocker. Even so.]
Consider the iOS management profile from NextDNS along with a good set of their filter options (minimally NextDNS + AdGuard), enabling 1Blocker and learning how to tailor it, and turning on Apple’s native anti-tracking — then with all three in place enjoy browsing the web with relatively less footprint.
Web browsing in iOS is incredibly frustrating and privacy-unfriendly compared to Android. I recently bought an iPhone for the app tracking protection, but the difference between Safari and Firefox is like night and day.
For example: you cannot install NoScript, or anything like it, on an iOS browser. You must choose between "all JS on" or "all JS off", and third-party browsers like Firefox are crippled because Apple forces all iOS browsers to use their WebKit engine under the hood.
The myriad of Safari "content blocker" apps are also pretty dismal, and often expensive. So ad-blocking is difficult as well.
They're better about app tracking, but you might want to keep an Android phone handy if you enjoy browsing the web.
