Have you seen <https://bugzilla.redhat.com/show_bug.cgi?id=1703745>? This indicates the messages are due to wpa_supplicant not properly handling your wifi hardware, so you may want to check upstream. This could be an issue with the firmware version provided by Fedora. My Fedora 33 system has wpa_supplicant messages in "the systemd(1) journal as written by systemd-journald.service(8)." so either Fedora 34 has changed logging for wpa_supplicant or you have a local wpa_supplicant version/configuration. This sort of problem often appears across multiple linux distros, so it is worth checking for similar issues on other distros, in particular Ubuntu and Arch. -- George N. White III
