Safari Pop Ups In - Iphone XS

Was in safari browsing local city events and came across a local website. When I proceeded to the website, I received a pop-up "Your iPhone has been compromised. Immediate action required." The only option was "close", of which I clicked and was re-directed to what appeared to be a malicious website with further redeem & download like type links for virus removal. Of course I did not give any information or download anything when I was redirected to the new page. At that time, I opened another webpage and searched what to do & eventually closed all windows, updated from 12.4 to 12.4.1, cleared history & data, all apps, my password, and re-booted. Anything to come of simply clicking close on the pop-up due to instinct :( ? Is there anything I need to do further? I am concerned personal info was stolen or actually compromised. Or perhaps adware and not compromising by any means?
