Whenever I try to connect my iPhone to my MacBook Air with the USB/lightning cord, it just keeps connecting & disconnecting. Won’t stay connected. Do I just need a better cord? To clean the USB port? The same cable works on a charging block just fine.

I’m going to answer my own question, hopefully it will help some people. I bought an Apple brand USB-Lightning cord. That did the trick. No glitching, transferred data and charged with no problems. I guess I should have just spend a little extra $ on name brand stuff long ago.
For me it was not even connecting. My solution is go to settings on your mac then to Privacy and Security. In that "Allow accessories to connect" change it "Automatically when unlocked". It worked for me!
I have the same problem, and would also like to know the answer or a reasonable work-around. -- It seems to me to be a subtle connection issue, in my case concern an USB-A port on two of my 15-inch MacBook Pro that are able to provide power but seemingly both have a (for me) spurious problem with the data connection.) [Thank you for formulating this as a question, it concerns an issue that bothers me much. Best wishes.]
