Answer 1

I'd advise on using the pnp/sp library (if you're developing in JS/TS) and leverage the clientside pages api.

From a purely technical standpoint, you'll find two columns in the SharePoint Pages Library that contains information pertaining a page rendering/appearance/contents: CanvasLayout1 and LayoutWebpartsContent, both contains a sort of XML with escaped JSON within. You may reverse engineer existing pages to try and generate your own
