I don’t believe this is the case. 3 is fairly robust, and 2 is still just brute forcing, though rapidly on a local CPU. The one that’s trivial is trivial to crack is WEP.
WPA2 is pretty trivial too. Not as easy as WEP since you do have to locally brute-force the PSK (password), but that's pretty quick on modern systems. We had multiple assignments when I was in college that had cracking a WPA2 password as a step (in the interest of time, the instructor used passwords from the RockYou list but still)
Yeah, if you’re using common words or variants thereof, you’re gonna have a bad time. But a 128 character string of random characters is going to be functionally safe from such an attack, for now.
And you'll go crazy every time you try to add a device that doesn't support QR code scanning.
Just use multiple dictionary words with a symbol or two thrown in. Or go all out and set up 802.1x with client certificates and save the PSKs for a firewalled segment of less important crap.
Although it's worth mentioning that wireless security means nothing to jamming. Jamming is RF, it's destroying layer 1 before WPA matters.
