Per my OP, see this dmesg output (this from Armbian which was running with full networking at time of ethernet loss. I haven't done so much troubleshooting with other bootable OS images, instead just checked for presence of any network with ifconfig and/or nmtui.):

[edit] USB wifi dongles are detected and configured without issue.
