I used to have a separate Cloudflare account with a separate DNS Zone for my internal services. Because CF PATs were free-for-all. They've improved this since, so now you can create a token scoped to a single Zone. If you really care about, you can move a subdomain to a separate zone with a child NS record, but I haven't tried it with cloudflare. If you are using something like AWS, you can create an IAM role that can only update a single DNS record.
Moving subdomains to separate zones can make sense for a small set of subdomains and all your certificates would be for names under those subdomains. It gets unwieldy if you have to create a separate zone for each certificate because the certificates don't share a subdomain. But this can be a solution in some circumstances. Thanks.
I see that AWS permissions can be set to limit the risk of compromised credentials. That's a good idea. I see that the lego project has an example of this in their documentation: https://go-acme.github.io/lego/dns/route53/index.html#least-...
