So it sounds like I should just place things and route all the traces that aren’t ground, without worrying about isolated planes on the front, and then connect them to a solid backplane with vias?

If you want to learn more read pdfs I linked here some time ago:

Decoupling capacitor via placement

I didn’t read that book but I suppose you can replace it with: I think it is enough for most pcb designers.

and

Decoupling capacitor via placement

About 2004 I found an interesting serie of EMC articles by Keith Armstrong (for many years I didn’t know if Keith is a woman or men name). Later they became no accessible, but when I tried to find them few years ago I found them once more: http://www.compliance-club.com/pdf/DesignTechniquesPart1.pdf http://www.compliance-club.com/pdf/DesignTechniquesPart2.pdf http://www.compliance-club.com/pdf/DesignTechniquesPart3.pdf http://www.compliance-club.com/pdf/DesignTechniquesPart4.pdf http://www…

And also, I should avoid long power runs?

Those power tracks were questioned because they cut your GND and not because they were long.
