These binaries are built from the official cloudflared GitHub repository and hosted at cloudflared.bowring.uk
Cloudflare provide official builds for macOS, Windows, and various flavours of Linux over at github.com/cloudflare/cloudflared but there are no builds for FreeBSD as of yet :(
Most people can probably manage by installing the native cloudflared FreeBSD port or package, but for systems that can't use pkg (such as TrueNAS) the compiled binaries are provided here.
Updating can be scripted by getting the hash of the latest version from cloudflared.bowring.uk/binaries/cloudflared-freebsd-latest.sha1 and comparing this to the currently running version. The latest (compressed) executable can then be obtained from cloudflared.bowring.uk/binaries/cloudflared-freebsd-latest.7z which will redirect to the latest built release.
The update-cloudflared.sh script automates this checking/updating/unzipping process and will also restart cloudflared once updated.
