Those are all drastically different devices.  What 802.11 standard are you looking for  (g,n,ac,ax ?)

This is probably the best list out there.  https://github.com/morrownr/USB-WiFi/blob/main/home/USB_WiFi_Adapters_that_are_supported_with_Linux_in-kernel_drivers.md

Edimax EW-7811Un V2 (seems to use rt8192cu) ...

I think you meant rtl8192cu. Spelling, punctuation, and
capitalization matter.

If you have network access on your pi, you can ask it.
Here is an example from TC10 x86:

--- Code: ---tc@E310:~$ provides.sh rtl8192cu
firmware-rtlwifi.tcz
wireless-4.19.10-tinycore64.tcz
wireless-4.19.10-tinycore.tcz
--- End code ---

Or on any machine with a web browser, go to:
http://tinycorelinux.net/15.x/armhf/tcz/provides.db

Search the page for rtl8192cu. Then page up until
you get to the .tcz that supplies it.
The first entries found will be firmware.
Later entries will be drivers from a different .tcz.

Just something to connect the Pi to WiFi, the mt7601u one did work when loading the modules in the correct order, but the adapter itself is a bit shit and the connection kept dropping. Probably because it's really cheap, so looking to buy a better one.
Not PiCore's fault, same thing happened on Debian.
I'll check provides.sh and see which ones are available.
Buying them on Amazon so can always return if it doesn't work, will report back with results.

While it is likely that device is supported, posting the
result of lsusb for an actual device is the best way to
know for sure.

Tp-link has used several different chipsets for this device.

I noticed for rtl8192eu there are three firmware files:

lib/firmware/rtlwifi/rtl8192eu_ap_wowlan.bin
lib/firmware/rtlwifi/rtl8192eu_wowlan.bin
lib/firmware/rtlwifi/rtl8192eu_nic.bin

for most others there is just rtlXXXXXXfw.bin

Is there something different about that module?

Rich:
Hi bradwiggo
This is just guesswork:
lib/firmware/rtlwifi/rtl8192eu_nic.bin Might refer to an actual Network Interface Card (non USB)?
lib/firmware/rtlwifi/rtl8192eu_ap_wowlan.bin Possibly allows the device to act as an Access Point?

When all is said and done, the driver selects which firmware to use.
Q. How do you know that?
A. I've seen firmware show up as a dependency when running modinfo on a driver.
