Regarding Bluetooth/external keyboards: The last time I tried an iOS terminal app, iOS had limitations on many key combinations, such that I couldn't effectively use Emacs with normal mappings (or Bash with default Emacs-style keyboard shortcuts). Has Apple changed this and if so, does Blink or any other app work properly in this regard? I'm not concerned with changing modifier keys, just want standard Ctrl and Option as Meta like I do in macOS.

You can do that on Blink, and it was one of the reasons why I started the project. Option as Meta and Cmd as Ctrl :)
