The DNS name resolution is actually not done by your system or ISP, but by a DNS over HTTPs (DoH) service (Cloudflare 1.1.1.1 resolver). Cloudflare seems to be respecting the TTL as returned by the authoritative name server for your domain, so if you are able to specify a short TTL for a TXT record in your domain control panel, any changes made to the website should be live within that time.

Triweb users are able to do that, but they don't necessarily know that they need to do that. For example, the Cloudflare DNS dashboard displays "auto" as a TTL by default, and one has no idea how many seconds "auto" is for a TXT record.
