Can you please show the ifconfig output after boot plus kldstat output?
Could it be you perhaps need to add a 'create_args_wlan0 statement to
rc.conf(5)?

I currently use: create_args_wlan0="regdomain ETSI country NL authmode WPA powersave" where iwm(4) is the parent interface.

I'm using lagg(4) with failover with laggports em(4) and wlan(4) so my
config is a bit different but for the laggports I have a
create_args_iface  in rc.conf(5)

Couldn't say but sounds plausible.
