The default key binding set is a de facto standard for double-pane file managers. I personally used Total Commander for a long time until I switched to Mac, and I really missed a FM with the similar hotkeys.
But I understand now that it's not what all Mac users expect from a file manager. I'll make an option to choose the hotkeys on the first launch [1].
As about the Touch Bar, Marta supports it since 0.1.2.

Yep: the app provides touch bar buttons for many operations
It works quite well for me.
Not sure about the touch bar though.
As for the Touch Bar, yes, that's a problem with the standard keybindings (and is also why I'll probably only be a macOS/Marta user for a few months, as I'll never buy a laptop with a fake keyboard).
But settings to the rescue! Cmd-shift-p & 'open default keybindings' reveals that they're all configurable.
I develop for several different platforms on macOS, and have never felt the need to enable that setting, because I've never encountered any macOS software that required the Fn keys in this particular non-idiomatic way. Even macOS IDEs stay away, tending to map things to complex key-chords instead.
Why? As a heavy emacs and Xcode user at least, I rarely need a function key, and prefer the convenience of the media keys.
