我想我已经破解了这个，多亏了Redditor\'s help.该建议实际上是：

从3和4开始（“使用get\\u posts（）构建与条件3和4匹配的post id数组”）

// 1. First, get all (4) Viewpoint (taxonomy term) (3) Articles (post type).
$vp_post_args = array(
  \'post_type\' => \'article\',
  \'tax_query\' => array(
        array(
            \'taxonomy\' => \'format\',
            \'field\' => \'slug\',
            \'terms\' => \'viewpoint\'
        )
    ),
    \'fields\' => \'ids\',
  \'nopaging\'  => \'true\',
);

// 2b. [Longlist for WP_Query] Then constrain by (1) Company (taxonomy) and its (2) Tag (ACF Checkbox) value.
    $vp_org_term_args_for_posts = array(
        \'object_ids\' => $viewpoint_posts_ints,
        \'taxonomy\'   => \'company\',
        \'meta_query\' => array(
             array(
                \'key\'       => \'tags\',
                \'value\'     => $tag_section,
                \'compare\'   => \'LIKE\'
             )
        ),
        \'hide_empty\' => false,
    );
    $viewpoint_org_terms_for_posts = get_terms($vp_org_term_args_for_posts);

此外，我发现这种用例是我需要在我的站点上的多个用例中使用的。

在某些帖子类型、分类法和元值的名称中进行硬编码会将代码提交给该用例。

所以我把它移到了一个灵活的函数中。以下是我对社区的第一次积极贡献，也是我能力的提高。也就是说，请随时进一步改进。。。

起始条件：我选择将分类法“格式”术语“视点”（即起始帖子中的我的维度#4）类型为“文章”的帖子移动到新的帖子类型“视点”。

功能：

/**
 * ==============================================================================
 *                      GET TERMS WITH EXTRA DIMENSIONS
 *  Gets a) Taxonomy Terms that have b) a Meta set and c) are associated with posts
 *  of a particular type.
 *
 *  This is how it works:
 *  1. First, gets IDs of all Posts of specified type.
 *  2. Then, uses that list to constrain getting a) Taxonomy Terms with b) Meta value set.
 *
 *  Arguments:
 *  1. Taxonomy name, 2. Taxonomy Meta Key-and-Value array pair, 3. Post Type name,
 *  4. get_terms \'orderby\', 5. get_terms \'order\', 6. get_terms \'number\'

 *  Example:
 *  $terms_list = get_terms_with_meta_and_posts_of_type(\'company\', array("tags"=>$tax_meta_value), \'viewpoint\', 11);
