> The only things missing are some keyboard shortcuts like Ctrl+A/V to move to the beginning and end, and the Ctrl+Shift+C/V behavior on the terminal instead of Cmd+C, which I've just worked around by using VSCode's terminal and configuring it to copy when I press Ctrl+C with some text selected.

The fact that you think this is acceptable shows that you don't appreciate the difference. Again, I haven't used Omarchy but the docs claim that Super + C and Super + V work everywhere, not with all the different exceptions you mention.
