I figured it out!
Thanks for all the tips. I had tried those suggestions before my original post, but I tried them again and a few other things.
In the end I tried flashing the sd card from a different computer with built-in sd card slot. After that, everything worked as expected and the phone booted from the SD right away and installation resumed no problem. It seems the usb card reader I was using was the issue, though it seemed to be working correctly, somehow the image was corrupted during the flashing or ejecting of the card.

Wouldn't boot from SD, now won't even power on
