For me, in the xfce4-panel notification area only icons are shown. That is, if an app sets its label without an icon, its not even visible. The label is not displayed when using libappindicator3 set_label function. Though this seemed the main method of displaying an app indicator. I do not know if its a bug in libappindicator3, xfce or is it intended to only show icons. Any information would be helpful.

This is for sure the wrong component because the internal notification area only supports legacy systray items. Please check if you're using the indicator plugin or the statusnotifier plugin.
I'm using this one: https://docs.xfce.org/xfce/xfce4-panel/4.12/systray
Ok, in this case yes, this is the legacy systray and it doesn't support text/labels: https://developer.gnome.org/gtk3/stable/GtkStatusIcon.html
Ok, thanks for making that clear. If I understand correctly, the statusnotifier plugin does support app indicators and labels will be shown?
Yes, the statusnotifier and/or the indicator-plugin should have this feature in general.
E.g. indicator-power shows the percentage / remaining time in the indicator.
