Hi Maverick,

I am sorry, but our Support does not include writing or debugging Custom SQL Queries for our users.

I can see you started to get part of the data you need, and now you need to get the additional data from ACF, we will do our best to at least advise you what are our current tools you can use and where you might search for help with Custom Queries from the WP DB.

As the custom posts/fields and ACF, are a part of the WordPress database;

pulling this data can only be done through custom MySQL query-based tables.

Please note: Using this plugin feature requires at least a basic knowledge of SQL. It is assumed that you can create the table in some MySQL data manager (e.g., PHPMyAdmin, MySQL Workbench), and prepare a SQL query that will return the data you need. 

A good way to achieve this can be experimenting using our WPDB SQL Query Constructor tool.

You can also try this other SQL Query helper Tool,

Create a MySQL-query-based table by querying a database,

that one has a wider range of all tables you can choose from your Database outside of WPDB.

- Please note: this tool is not an ultimate query generator. It simply constructs a suggestion of a query. We are constantly working to improve it, but SQL is such a complicated and flexible language that full automation for constructing queries is next to impossible. 

Consequently, the more complicated the query, the higher is the probability that it will not return exactly what you need. So, you will often need to play around with the resulting query.

Please be advised that writing custom SQL Queries or debugging Queries does not fall under what our support covers.

You can additionally check out this official page of WP codex,  for help with writing custom Queries.

I hope that helps.
