Ubiquiti Cloud Gateway: install via SSH and CLI or simply enter DNS-over-HTTPS URL into UniFi OS?

I see the provided CLI script and I am capable of SSHing, but I'm wondering what the exact benefits of using the CLI over simply entering the URL into the UniFi UI are?

Are there things that can be configured by the CLI that I can't configure on my profile at https://my.nextdns.io/?

Is the CLI simply a way to do it from earlier times before UniFi offered a way to do in their UI? Or are there still advantages to using the CLI?

CLI Instructions I'm referring to: https://github.com/nextdns/nextdns/wiki

Aside, after reading https://help.nextdns.io/t/x2hmvas/what-is-dns-over-tls-dot-dns-over-quic-doq-and-dns-over-https-doh-doh3, I'm convinced to use DNS-over-HTTPS. If anyone is wondering why I specific in the title.
