Sounds like you want EndeavourOS.
Installs in a few minutes to a fully configured and usable desktop environment of your choice. It is Arch ( uses the same packages, uses the same kernel, has access to the AUR ). A huge benefit of the Arch repos is the up-to-date package universe as well everything you are likely to want being in the repo or AUR.
Don’t underestimate the maintenance and reliability benefits of not having to cobble stuff together from multiple sources.
I use the version of VirtualBox that has been modified to use KVM as the back-end. Do you know if it has the same problems?
