I did a small Automator action that just switches dark mode on my computer, and I activate it with the cmd-alt-shift-P hotkey; it’s truly convenient and there’s no need for a third-party :)

    osascript -e 'tell app "System Events" to tell appearance preferences to set dark mode to not dark mode'

You can also use BetterTouchTool for that. I have CTRL-OPTION-CMD-M set up on macOS :)
