Nice to have:

Need to decide whether to have a means to recover and reduce the number of processes running which should improve memory matters etc

e.g.

1. Uninstall snapd if deemed not needed - this will remove budgie-welcome but with the advantage of reducing memory needs
2. Untick desktop icons support - reduces memory slightly
3. dconf untick various gnome-settings-daemon plugins - lots of plugins are enabled by default - doubtful some of these are needed for a pi
4. Look much more closely at the number of budgie applets we have running - are they all truly needed? Will reduce the number of budgie-panel processes reported by ps -ef
5. Generally wander through ps -ef and look to see processes are running / are they truly needed and how they were enabled i.e. package that is installed that enabled the process(es)
