If you’re using an Intel chip look into GVT-g and consider running Arch from a VM, that’ll be the closest thing to native.
The unfortunate thing about running an Arch container from a Debian host is that you’re relying on an older kernel and an older systemd host side and I’ve found that often causes compatibility problems inside the Arch container. If you are very, very lucky Arch will just work inside the container, but IME that’s fairly rare as systemd often has breaking changes over several releases (and Arch tends to be at least several releases ahead of Debian.)
