So VHT is clearly there, which means it passed regdomain.

Country code was set correctly.

That was a think-o from me last night; I meant

sysctl compat.linuxkpi | grep iwlwifi

just to check that the loader tunables for 11n and 11ac did not get lost
but I believe otherwise they wouldn't show up in the channel list either
(my iwlwifi test devices are either busy or off currently so I cannot
reboot to double check; maybe just do so we are sure that they are like:
compat.linuxkpi.iwlwifi_11n_disable: 0
compat.linuxkpi.iwlwifi_disable_11ac: 0 ).


The only think I think could help would be a

ifconfig -v wlan0 list scan | grep xx:xx:xx:xx:xx:xx  where xx:xx... is your bssid.

and/or a radiotap recording of the association process; using a monitor node would
certainly be cleaner but you could locally run
tcpdump -ln -s0 -e -vvv -i wlan0 -y IEEE802_11_RADIO -w /var/tmp/for-bz.pcap

and then (re)start wpa_supplicant and let it record packets until ifconfig
says you are associated.  Please do not share that file publicly.
