between an EMU and say, a string of subway cars or interurban cars (like
what South Shore Line runs, saw some in Gary on my way into Chicago this
morning)... those have traction motors in each (or at least many of the)
truck(s) too.

Here those terms are actually pretty much synonymous with each other. All our
suburban trains are EMUs anyway.

What exactly does “suburban” mean in this context?.. is it like the US
“commuter” (meaning that the train is primarily put on to serve people coming
and going to and from work, and typically is heavy rail rather than light rail
or trolley, and often was originally operated by a freight railroad although
usually is now under the auspices of a commuter authority) or more like the US
“interurban” which really has muddy meaning, it originally meant streetcar like
vehicles that run primarily on private ROW and sometimes connect more than one
city instead of just being a trolley line... or something else?

1 - Although “MU” is... it is just the term for connecting two or more
powered(1) cars or locos together so they can be controlled from one control
position.

Messed up, not mixed up. A mix up is when at least two different things are put
in the wrong place, in this case it was only one wrong thing.
Nice try though!

2 - technically not necessarily even powered, actually. In push pull
service, all the cars have MU cables running down them so that the unpowered
last car can control the locomotive when running in push mode.
