Yes. The most important thing here is that 1.1.1.1 is announced in seriously a lot of places. I just went to Hurricane Electric's looking glass, several times picked 3 routers at random and put in 1.1.1.1 as the destination. All of them returned it as the 2nd hop, meaning it's most likely announced in the same exact datacenter as where HEs router is located.

That gives you all the redundancy you'll ever need. Of course, you need to rely on Cloudflare to not mess it up. But you're not going to do better than CF.
