SetupStatic is meant to be used with static constructors. In order to mock an instance constructor with arguments you can use Mock.Arrange like this:

        var expected = "StringArg";
        string arg = null;
        Mock.Arrange(() => new A(Arg.AnyString)).DoInstead<string>(x => arg = x);

        new A(expected);

        Assert.Equal(expected, arg);
