WPA3 SAE setting more secure than mixed WPA2/WPA3 PSK, SAE?

I have a strange situation with some android phones.

If I set the openwrt router to "mixed WPA2/WPA3 PSK, SAE (CCMP)" the openwrt access point is recognized and the phone says the connection is WPA3 Personal.

If I set openwrt router to "WPA3 SAE (CCMP)" the AP is not recognized, but I could configure WPA3 Enterprise manually with the phone. No idea if this would work then.

So my question is, if it is less secure to allow "mixed WPA2/WPA3 PSK, SAE (CCMP)" with openwrt, while the phone says it uses WPA3 Personal then.

Or is it more secure to limit to "WPA3 SAE (CCMP)" in the openwrt configuation?

Can I setup WPA3 Enterprise with openwrt? Is there a tutorial how to do this? Some phone allow to select WPA3 Enterprise and others allow WPA3 Enterprise 192bit too.

Mixed WPA2/ WPA3 is always less secure than WPA3SAE, as the client (or an attacker impersonating it) can always downgrade the encryption to WPA2.

That is my opinion too. So I tried to avoid "mixed".

In the meantime I think the phone does not support WPA3 Enterprise, it is an option only and generally offered.So I fear I have to stay with mixed.

I have very strange behavior with my APs. I trust in the detailed internet info of the phone.

The routers are now set to mixed. Wifi analyzer app says, all the openwrt routers support WPA2 and WPA3.

Connecting a phone to 2 Archer C7 the same phone says WPA3 Personal, but when I connect it to a Netgear EX6150v2 it says WPA2. If I connect another phone to the EX6150 it says WPA3 Personal. With a 3rd phone connection doesn't work to the EX6150 but to all other openwrt APs.

Maybe I should forget this minor problems and wait for the new hardware.
