The better setting is '(basic flex). With that setting, there is no
problem at all. Try

emacs -Q -l tramp --eval "(setq completion-styles '(basic flex))"

This works out-of-the box, w/o any further patch (as you have said above).

If I do instead

emacs -Q -l tramp --eval "(setq completion-styles '(basic flex))" -f fido-vertical-mode

it doesn't work. Debugging of fido-vertical-mode is needed, I suppose.

Best regards, Michael.
