We recently had to revisit this due to a separate issue, and time had provided a little insight (I think!).  
To summarize, for future reference:

To get a working setup on RHEL 8 with Xfce 4.16.1 (from EPEL), two changes are needed from OSC’s baseline **script.sh.erb** :

1. A message bus for the various Xfce components has to be manually launched (`dbus-launch`)
2. The window manager `xfwm4` has to executed in the background; [the `--daemon` option is no longer valid](https://gitlab.xfce.org/xfce/xfwm4/-/commit/43e76c7bdfa6db6bf95f576723dc5e41cc15f59e)

Here’s the parenthesized block of Xfce commands we’re using with success:

```auto
# Launch Xfce Window Manager and Panel
#
(
  export XDG_CONFIG_HOME="<%= session.staged_root.join("config") %>"
  export XDG_DATA_HOME="<%= session.staged_root.join("share") %>"
  export XDG_CACHE_HOME="$(mktemp -d)"
  eval $(dbus-launch --sh-syntax)
  xfwm4 --compositor=off --sm-client-disable &
  xsetroot -solid "#D3D3D3"
  xfsettingsd --daemon --sm-client-disable
  xfce4-panel --sm-client-disable
) &

```
