What he probably meant is that Command+C is copy, etc.
You can’t easily do that because every Linux program expects different things. The hack to make it work is to switch keyboard configs when you switch the application, I think. It’s far from ideal.

Just posting here too, I've plugged into evdev to remap keys so the keybindings work on all apps and in gnome Wayland. https://github.com/csumtin/cua
I also use a customized layout (mostly international English with shortcuts for German Umlauts and Y and Z remapped to eachother). It definitely works in most modern Linux desktops to use a "custom keyboard layout" like described here. There are many guides which are outdated on the topic. It's a hack and also not super simple to execute (you only need to do it once) but it is persistent and system-wide in all programs at least:
