You can probably achieve this in a plugin by doing something along the lines of:

- with the plugin API add a [`api.addSaveableUserOptionField("composer-custom-font")`](https://github.com/discourse/discourse/blob/3ab8e66c00cfd89890cf57275ff1777f85ec2c86/app/assets/javascripts/discourse/app/lib/plugin-api.gjs#L2318-L2320)
- add the field to the `UserOption` table in the db and the serializer so it can be set
- add a connector to the user’s interface page so the setting can be set
- you can make the setting a dropdown, for example, so if the user picks a certain font/font style it adds their preference in the db
- you can extend the composer code to take into account their selected preference, and either change the styles directly with JS or make it add a CSS class based on the preference chosen, which you can apply styles via CSS for that specific class
