Somewhat, but the relative new systemd inside Debian 10 and other
newer distros is not always that compatible with current Container
Environments.

As a starter I'd enable the "nesting" feature in the CTs options, it
should help for quite a few issues by allowing systemd to setup it's
own cgroups in the CT. This option can only be done as root, and while
it has no real security implications it still exposes more of the host
in the CT.

There's some work underway to improve the CT experience with newer
distribution versions, but that will need still quite a bit of time and
will only become available on the PVE 6.X series, AFAICT.

No, while the enterprise version is surely more stable it has not more
features than the community ones.
