Leaving this here in case anyone wants to try this since Parallels only fully supports whatever version of Android can be installed through the New VM thing. Currently that's Android 8, which works fine.
Was also able to get Android 9 working by downloading and using the image from Android_x86. The trick is to add 'nomodeset' after 'quiet' in the kernel boot line in grub. Otherwise, the boot sequence stops short of starting the gui with a #console prompt.
Unsure if this trick works in Android 10 as well, but it's worth a shot if anyone's having a problem.
Now if there's an easy way to get to the boot partition to permanently modify grub.config...
