I know Fedora Linux is well known for ‘secure by default’. However, some people with curious mind and informed users may want to understand what’s behind the façade (graphical installer) and know what advanced mode there is in OS and application level. Network stack and physical security are a different matter.
FreeBSD and OpenSUSE give options to customize during and after installation explicitly in graphical installer, so anyone who wants to touch ‘advanced mode’ has options to configure, or you can ignore them by clicking ‘no’.
