Observation: WAC5xx Update 22.214.171.124 - Changed SSID from WPA/WAP2-Personal to WPA2/WPA3-Personal
Ok, updated a bunch of sites (Insight and local Web managed) to WAC5xx APs to 126.96.36.199 firmware.
Found the Microsoft Windows 10 Pro (64-bit) Version (Build) 2004 (10.0.19041) with Intel AX200, Version 188.8.131.52 Date 4/5/2020 drivers continued using WPA2-Personal only. Disconnect and reconnect, or reboot has not made a difference. Had to "forget" (tsk, fells like an iOS/iPad OS and MacOS system lol) the stored connection (automatic or manual connection does not make a difference), and discover and re-configure the wireless connection again - and bingo, now it's using WPA3-Personal reliably. Suspect Win 10 does "keep" the previous security level why ever.
According to Inhell: https://www.intel.com/content/www/us/en/support/articles/000054783/network-and-i-o/wireless-networki...
...this should be fine.
