Will plugging in Ethernet Cable mid-WiFi Screen Share disconnect link?

I'm in the middle of doing a Screen Share / Large File Transfer and just realized that I'm doing this via WiFi. Realizing that this is going to take some time, I thought I might plug in the CAT5 Ethernet cable from my modem into the back of my iMac, but fear that I might interrupt the transfer.

On another note, if I finish transferring the file, THEN decide to switch over to CAT5 (vs. WiFi), will this disconnect me from the target computer? The person who owns the other computer has gone out for the night, so if I get disconnected, there's no way I can continue with the project/transfer until they grant me access again.

If you've already started the transfer via WiFi, plugging in the ethernet cable will probably not do anything until you stop WiFi and then select ethernet. However, it's best not to mess with anything if the transfer is well along. I'm sure about your second question, but just to play it safe I would not switch over if no one is at the other end.
