I don't doubt these are more elegant than the Office suite.
But I have multiple versions of Adobe InDesign between work and home. Pages seems very limited to me and actually more like Microsoft Publisher. QuarkXPress is better as well. And Affinity has released Affinity Publisher to beta (finally).
Of course, these may be overpriced and overqualified for what you're doing. But I'm a Graphic Designer by trade so I tend to use these tools.
Quark: yes. no substitute. i agree.
