It's fun to learn a bit more about how wifi and encryption works by cracking it using something like aircrack-ng. There's not really any other practical use unless you have bad intent or are planning on entering the security field.
I would agree that curiosity is the biggest driver here. A while back I played around with kali and aircrack-ng and was eventually able to crack one of my neighbors WiFi (big city - lots of signals). Even entered the router which was set up with the “standard credentials” of its type. But in general it’s very unlikely that you will successfully crack any WPA2 Wi-Fi signal. If you want to crack a specific signal it gets even trickier…
FWIW that's illegal and is considered hacking in the US and can result in jail time. You should only do this on equipment you own. Not saying you did anything particularly nefarious or that the chance of getting caught is high but just FYI.
