Can’t one SSID support different WPA versions across APs? I’m pretty sure all my devices just shrugged and connected when I downgraded my (single AP) SSID from WPA3/2 to 2 only and back up to 3/2.
Which is a bit sad, but also seems like it would allow this use case perfectly (assuming this was done on purpose and not just an oversight).

I think so, yes. My OG Nintendo Switch connects to the PSK SSID on my two OpenWRT Ones that's using what OpenWRT calls 'sae-mixed' encryption mode. My PCs (using ath9k and rtw88_8822be drivers) and my Pixel 5a connect just fine to my EAP SSID that's using the 'wpa3-mixed' encryption mode.
wpa_supplicant says that the PSK SSID has "SAE" in two out of three of its supported operating modes, and the EAP one has "EAP-SHA256-CCMP-preauth" in one of the two. [0] I assume that means that they support WPA3 operation, but I don't know for certain. I'm somewhat ignorant about WPA3, and am profoundly ignorant about WPA3-EAP.
[0] I'm assuming that the "/"-separated list that comes after the "WPA2-" bit in wpa_supplicant's scan results is a list of what I'm calling supported operating modes.
