>The ISP learns about the result regardless right after the domain name has been resolved to an A/AAAA record, when the browser sends the TCP+SYN packet to start HTTPS.
not necesarilly. With HTTPS the ISP will see the IP being connected to, not the domain. Since there can be multiple domains behind a single IP address, the ISP cannot know the exact domain. On the other hand since more and more websites use cloudflare revproxy service, quite often all the ISP will see is one of cloudflare IPs being connected to, whereas Cloudflare will know the exact domain (and URI) your browser is requesting. And Cloudflare will get that information regardless of the way you look up DNS record
