That is a hard question to answer, without direct experience on Macbook hardware.
If you do push ahead with actual installation on one (or both) of your Macbooks, check this advice from Aravisian re using rEFInd. Issue Booting Zorin OS 17 USB on Macbook AirUnable to Boot Zorin OS 17 USB on Mac - #2 by Aravisian
EDIT: I just did websearch using "Broadcom BCM43xx Ubuntu 22.04" (as Z17 based on Ubuntu 22.04) but see no solution: 22.04 - Connect to Wi-Fi on MacBook Pro with Ubuntu 22 and Broadcom wireless adapter BCM43602? - Ask Ubuntu
I don't know if this will help you, or others here with relevant experience to help you. WifiDocs/Driver/bcm43xx - Community Help Wiki
