Double Click the second Section Break (on page 2) and set the Margins using the Option to "Apply to:" = This Point Forward

Did you try this? For me, the margin settings in the dialog are the same in both sections.

Yes. Results created consistent margin settings for each section. There are still different indents and tab settings. A separate Style should be consistently applied or all elements changed to objects (Picture and Text Box)
However, I'm not sure why the choice of Section Breaks over simple Page Breaks. The document would likely be better served using a cover page instead (maybe? I've not used often to be wary of all the pitfalls of Cover Pages.)
If Section Breaks should be used, I would apply those Section Breaks last based on the process of Content, Format, Layout.
