What is the difference between Kicksecure GUI and CLI?

I’m thinking of creating a minimal Kicksecure template to use for my sys-qubes but I am not sure if I should install the GUI version or the CLI version of Kicksecure. What difference does it make for the specific use case of the sys-qubes? I’m also wondering what mix and matching the debian templates (XFCE and minimal) with the Kicksecure versions will lead to. For example, if I start with minimal Debian and then install Kicksecure GUI, will Kicksecure install the missing packages that are not available in minimal Debian but are available in normal Debian?
