Not to get into WPA's many failures but purely in terms of auth: At this point WiFi and email auth alone I think is enough reason to learn at least very minimal free MDM for your devices and family devices. I think a fairly significant number of networks fall into the categories private personal (which mainly involve a limited number of specific users and devices), organization (which can handle better auth anyway), or public/guest (which should either be open/"open" or use a portal). In all those cases you can do away with ever needing to manually enter a password via supplying it via a profile, using RADIUS, or a portal, and in turn be free to just have any password itself match 2^256 bits. Even for edge cases I think better distribution strategies make more sense going forward then trying to figure out what an "easy" password can be (and how to rotate it) while still being secure. Just like password managers with websites, we're past the point where we should be using human memory or manual input in general at all.
