Sadly in practice the USB-C port still is one of the weakest parts of the phone. When it becomes too loose / mushy / unreliable, and cleaning it does not help, and replacing it is not economical, then that's it for the phone.

I've replaced the USB port (i.e., bottom module) in two of my (Fair)phones, both times because of wear or damage of the port.
