Hi,

I think most categories you'd call organizational (or maintenance)
categories will be subcategories of [[Category:Hidden categories]], so
you can query for that. There might be a more precise way to do it,
but that's how I've been distinguishing the two.
On quite a few wiki's (at least Commons) all non-topic (what you call
organizational) categories should be hidden categories. I hope you're
not doing recursive queries. You can see if a category is hidden in the
page_props table. For example:
MariaDB [enwiki_p]> SELECT * FROM page JOIN page_props ON
page_id=pp_page AND
page_title='All_articles_covered_by_WikiProject_Wikify' AND
page_namespace=14 AND page_is_redirect=0 LIMIT 1;
+----------+----------------+--------------------------------------------+-------------------+--------------+------------------+-------------+----------------+----------------+--------------------+-------------+----------+--------------------+----------+-------------+----------+------------+
| page_id | page_namespace | page_title
| page_restrictions | page_counter | page_is_redirect | page_is_new |
page_random | page_touched | page_links_updated | page_latest |
page_len | page_content_model | pp_page | pp_propname | pp_value |
pp_sortkey |
+----------+----------------+--------------------------------------------+-------------------+--------------+------------------+-------------+----------------+----------------+--------------------+-------------+----------+--------------------+----------+-------------+----------+------------+
| 36624356 | 14 | All_articles_covered_by_WikiProject_Wikify
| | 0 | 0 | 0 | 0.204521342345 |
20160315234552 | 20160123181102 | 546385235 | 261 |
wikitext | 36624356 | hiddencat | | NULL |
