Not sure what I was missing before but I finally managed to connect it... I didn't had to change anything in Moode, I only set my router to accept WPA2-PSK and restarted the router and the Raspberry Pi.
I double checked and having WPA2-PSK/WPA3-SAE mixed mode still won't work with the Raspberry Pi, none of my other devices in my home ever complained about this, only the 2 raspberry PIs and even those won't complain with older firmware like I said...
Not sure if this can be fixed in Moode, but I guess this should be at least reproducible if you have a router that supports WPA2-PSK/WPA3-SAE mixed mode.
Edit: Moode also connects without problems to WPA-PSK/WPA2-PSK mixed mode.
