You’re referring to creating whonix-ws with Qubes manager.
“provides network” is not set for anon-whonix (workstation AppVM)
“launch settings after creation” can be set only if you want.
“Provides network” is only for Qubes that will be providing networking for other VMs. For example, this setting would be checked for a VM such as sys-whonix since it provides networking (aka NetVM) for anon-whonix VM. This should not be set for anon-whonix VMs
“Launching settings after creation” only launches the settings GUI page so users can make further changes to that VM’s settings. It can’t hurt to set this option.
