I did indeed try the following drivers from various git repos and sources:

the one recommended through that thread I attempted:
# git clone https://github.com/MingxuZhang/rtl8821cu/

followed with cd to the dir, and a make which errored out with:

I'm unsure which of the git repos you were attempting to reference, as well I'm wondering, the command you posted referenced a different device in comparison to the one I've discovered via lsusb: 0bda:1a2b

=================UPDATE=======================
I managed to get the following git to compile as well as install

git clone https://github.com/brektrou/rtl8821CU.git

after which I did make and make install with success; unplug/replug did not modify the output.

HOWEVER!! after which I ran:

usb_modeswitch -KW -v 0bda -p 1a2b

the results of which are here --> https://termbin.com/nvfc

and voila, worked.
