AX3 not connecting to wifi network in station mode

In the snippet of configuration you posted, you have no passphrase set (maybe you edited it out? Or it the default "sensitive switch" that doesn't display it?)

Usually (but not necessarily) a profile is created in:
/interface wifi configuration

settings go there and you apply the named configuration to the interface(s).

The passphrase should show in
/interface wifi security

Check that you have it.

Anything in log? (when you try scan and then connect)

Try replicating this set of configuration:

Try with just one wifi interface at first, either the 2.4 GHz or the 5 GHz one (BTW you only have wifi2 in bridge, if this is intended, fine).
