For Chicagoland the MPO is the Chicago Metropolitan Agency for Planning engage.cmap.illinois.gov and we need a Federal that would push through the coordinated transportation investments you have in mind, for all of our major metros.

The actual line drawing of what's exurb vs suburb is murky. But acknowledging the existence of a line reflects that there are real societal costs to endless sprawl and driving, which is I suspect close to how those urbanists you referred to use "suburb". Which is not helpful.
valid arguments that there are many changes we should make about powers for levels of government covering different areas, and transportation infrastructure between municipalities fundamnetally depends on that, but within our framework MPOs leveraging federal funds are the best mechanism I know of
