CCloudflare name servers are a way to uniquely identify an accountehh, it's not like only your account has those two nameservers. They're not unique unique, although perhaps unique/rare enough to identify a pattern (side note: if there ever happened to be a collision with another cf account already having the zone added with overlapping ns's, it'd just pick two more different)
is it possible to switch up the name servers for each new zone for enhanced privacy?Sure, just preset your two normal ones at your registrar, wait a bit, add the website to Cloudflare, and you'll get two random other ones that you should then change your domain to at your registrar
