What’s difficult to use in Hetzner or DigitalOcean?

Apart from the payment part, this could be used entirely from a machine without a GUI. You can do the same with others using Terraform or aws-cli but it requires setup first.

What about SSH requires GUI?

I mean I SSH to my Hetzner Ubuntu fun box usually from Powershell or PuTTY, but sometimes I SSH from a Debian server without any GUI.

How did you provision your Hetzner Ubuntu fun box in the first place? That's the part that usually needs a GUI

One thing can be simpler than another without either of them being difficult.
