Assuming your phone is definitely connected to your network's Wi-Fi (and not cellular), it could just be a coincidence. You haven't mentioned what phone, what app, or what speeds, but there are plenty of potential bottlenecks in actual wireless transfer speeds. The biggest is perhaps that ac1200 does not mean you will get 1200Mbps data throughput. Even in fairly ideal conditions, it will be much less than that. You could also be limited by the speeds of your computer hard drive and/or phone.
To verify that your internet connection has nothing to do with it, use some method of examining that traffic. If your router/modem has any kind of dashboard indicating instantaneous bandwidth usage, use that. Or use Wireshark on your computer making the FTP transfer and verify the sources and destinations.
If your highest priority is transfer speed, it's pretty likely that USB is the best option.
