For clarity: The iwlwifi is a kernel driver for Intel wireless chips. The net-wireless/iw software can be used to manage the wireless association with an AP if the latter has been configured to offer connections with the deprecated and insecure WEP, or no encryption. The net-wireless/wpa_supplicant software can be used to manage the negotiation for a wireless connection with an AP when this has encryption enabled (WPA, WPA-2, WPA-3). The net-wireless/iwd is a more modern software developed by Intel to replace wpa_supplicant. In addition it will also create wireless interfaces as it needs to and manage these, as opposed to leaving this function to udev. Essentially iwd takes over the management of wireless interfaces and their encrypted communication with an AP in a standalone fashion. I haven't tried this yet to find out how it behaves, but it is rumoured to be more polished than wpa_supplicant and can work without netifrc scripts or dhcpcd. There are GUI front-ends for the above to suit various desktop and user preferences, some more polished than others.
