Does this mean that Flycheck should override M-g l too, or will that work automatically (how will M-g l know which one to pick?)

These are the relevant bits of Flycheck's map, I think:

    (define-key map "c"         #'flycheck-buffer)
    (define-key map "C"         #'flycheck-clear)
    (define-key map "n"         #'flycheck-next-error)
    (define-key map "p"         #'flycheck-previous-error)
    (define-key map "l"         #'flycheck-list-errors)
    (define-key map (kbd "C-w") #'flycheck-copy-errors-as-kill)
    (define-key map "s"         #'flycheck-select-checker)
    (define-key map "h"         #'flycheck-display-error-at-point)
    (define-key map "H"         #'display-local-help)
