Conclusion: on the Fedora Linux 37 Live iso the Wi-Fi driver for this iMac is present, however it does not get installed onto its SSD when installing Fedora itself. Booted from the Fedora Linux 37 Live iso Wi-Fi can be configured and used to traverse the internet, however when booting from the installed iMac no Wi-Fi adapter is found and with that, no Wi-Fi network can be selected and used.
