So be ready for problems with "clipboard" if you will to use some remote access (SSH for example) ore even virtual terminals (Ctrl+Alt+Fn) on your local device.
Curiously, there are no such problems in FreeBSD with remote access (eg SSH) or virtual terminals. I have copy and pasted between virtual terminals locally (just confirmed again that it works in case I was imagining it). I can also copy and paste between a local system console (FreeBSD) and a remote system xterm (macOS) when logged in via SSH.
On FreeBSD it looks like it's a feature of the mouse daemon: [man moused yields] "The moused utility and the console driver work together to support mouse operation in the text console and user programs."
Maybe something more to pursue on Linux...
