You can bundle all of these in the flatpak if you don't want to bring
them to Debian yourself.

You can use what gnome uses

Simply speaking they either come in via Debian or via a flatpak. Heather
did some experiments with hosting the flatpak repo (we want one that
only provides free software).
For the default (GNOME based) install we'll likely have gnome-software
prefer apps using the phone's UI and design patterns over those that
dont.
