Magic Wormhole (https://magic-wormhole.readthedocs.io/en/latest/) if it's between OSes.
Between OSX, AirDrop works very well. I have sent >10GB files between Macs, quite quick as well.
I have never send a 10TB file so I wouldn't know. None of my drives are that large yet :)
I use the magic of AirDrop as well :) Unfortunately, sometimes I'm on my Linux machine (in which case python3 -m http.server works just fine), or need to send a file to someone else and then I'd like to have at least some form of monitoring/progress.
Edit: magic wormhole is awesome! Thanks! :D
OpenDrop works very well on linux for airdrop between linux+macos.
Provided of course that you have a wifi card that supports active monitor mode.. and you are root on your machine.
