Make it simple and just use fedora. Has lots of the same benefits as openSUSE, except openSUSE allows you to choose any and all the software that should be installed through a GUI installer. You should be fine, use flatpak for the freedom from distro specific application packages, and the ability to harden flatpak sandboxing through Flatseal or native support in system UI. For a Windows looking UI, I recommend KDE Plasma which is available for Fedora as the KDE Spin edition, or natively in the openSUSE installer.
