Re: Still having trouble with saving BelongsToMany data

If Listings is the table being saved, having attributes, then there seems to be something wrong with your data.
I believe that your data should look like the following:

$data = [
    'attributes' => [
        [
            'id' => 3,  //provided the id is already known
            '_joinData' => [
                'value' => 'Off-street'
            ]
        ],
    ]
];
$listing = $this->Listings->newEntity($data, [
    'associated' => ['Attributes._joinData']
]);

Question: Did you try baking the models, making sure the associations were all correct as as you expected, then bake the controllers and views?  It seems that the bake utility should generate the code for doing this.
