I also feel for your loss.
From what you said you are more than just a simple hobbyist.
But I have one burning question, you bought an EOS 50D (not d50) for your first shot at Canon as a brand? A 10 year old used camera?
I can only suggest you use a Windows machine to try and format a CF card. I know it works. I do not know that using a Mac also works. Since I personally have not done so. Mac's are screwy but maybe it will work, too.
If the 50D does not see a pre-formatted CF card something else is wrong with it. I would urge you to seriously consider returning it and buying a more current camera.
If you bought an 80D or 90D, I am sure you would never miss those Nikon's ever again.
"Try a pre-formatted CF card"
Do you have a friend that has a Windows computer? Get them to format you a CF card. This is your only, easiest route to find out if the camera is OK.
