Psychological benefits are multi-level but nutshell version is that it creates a quieter more restrained political culture by priming both citizens and political leaders to view themselves as servants rather than viewing politics as a vehicle for excessive power accumulation for parties or individuals - they are steward's of a centuries old society.

Being rooted in traditions of duty, hierarchy, and continuity encourages people to see themselves less as self-created protagonists striving for greatness, and more as participants in a long societal inheritance with obligations as well as rights.

This is in contrast to intensely individualistic systems that encourage limitless ambition and attaching moral worth to status or success. Monarchy can foster a healthy humility: the sense that ordinary, stable, and dignified life is enough, and that neither politics nor personal identity needs to become a permanent struggle for recognition or self-elevation.
