And yes I know there are already threads about it. But each time I attempt it I run into a different issue, and I actually went backwards now. Note that so far all my attempts have been through GUI. Despite using linux for about 7 years, configuring network from console is still a slow, painful experience that I absolutely hate.
What I discovered very early is that on 2.4GHz, I can't have both client and access point mode network at once. Either one works separately, but both together give me "daemon.notice netifd: radio1 (11143): Interface 0 setup failed: BRIDGE_NOT_ALLOWED" in system log.
So what I thought I would do is connect client over 5GHz and create access point over 2.4GHz. And initially it seemed like I would succeed - I connected to my network over 5GHz and it created "wwan" interface. Then I created 2.4GHz access point, and set it to use that wwan network. It created a wifi network, but I couldn't connect to it without setting static IP address, and no matter what values I set it didn't actually work (no internet).
At some point I set "lan" network to "DHCP" instead of "Static address", and I couldn't connect over ethernet anymore. I fixed it by resetting the config in failsafe mode.
And this brings me to "now" where if I attempt to connect to the 5GHz network... it fails. Syslog points to authentication failure:

But I know the password must be correct as I can connect with the same password from my phone. Any idea what is going on and if it's even possible to configure it that way?
