It's not a long list. Choices so far would be wpa_supplicant or iwd.
wpa_supplicant is well known, so I'll write some information about iwd 
that I've collected in the last days.

iwd is a wireless daemon written by intel and supported by all major 
network managers. It can be run in standalone mode and configured with 
'iwctl' from the terminal, and with 'iwgtk' or 'iwdgui' from the gui. 
It can also work as a wpa_supplicant drop-in replacement for 
network-manager, connman or systemd-networkd.
iwd makes heavy use of the kernel api, so it is not portable but does 
not need additional external libraries like openssl. Instead, make sure 
that the following options are enabled in the kernel:

CONFIG_CRYPTO_USER_API_SKCIPHER
CONFIG_CRYPTO_USER_API_HASH
CONFIG_CRYPTO_HMAC
CONFIG_CRYPTO_CMAC
CONFIG_CRYPTO_MD4
CONFIG_CRYPTO_MD5
CONFIG_CRYPTO_SHA256
CONFIG_CRYPTO_SHA512
CONFIG_CRYPTO_AES
CONFIG_CRYPTO_ECB
CONFIG_CRYPTO_DES
CONFIG_CRYPTO_CBC

optional for wps support would also be needed:
CONFIG_KEY_DH_OPERATIONS

In standalone mode iwd can use either systemd-resolved or resolvconf as 
dns manager. Additionally, dbus communication must be configured. In 
the default configuration, iwd expects the user to be a member of 
either the 'netdev' or 'wheel' group.

As a backend for the network managers, I have only tested iwd with 
connman, which works smoothly and without additional configuration as 
soon as you make sure that wpa_supplicant is not installed. (connman 
will  look for wpa_supplicant on startup and will bring it up if it was 
found)

but you only want the information from the first sentence in the commit 
message, right ?
