> Cmd-Shift-P does the same as Emacs’ M-x

Only superficially, but not even close in practice. In M-x you can run recursive commands; you have history; you can search through history back and forth; you can scroll the buffer, shrink and widen windows, browse files - all without leaving the M-x menu; you can yank current command or insert directly into the buffer; select multiple commands; act on them; inspect the source; enable tracing; - these are all built-in features.

With some packages you can - export the commands list into a fully functional buffer from which you can still run the commands; you can cycle annotations - show description of the command or keys they bind to; you can display commands in a grid or temporarily flatten the menu for unobtrusive view. You can enable full vim-mode in it - in Emacs, M-x is a fully functional buffer, not some dummy input - I can call the LLM and ask it to find me a command while it's still active.
