Display a CPT based on a metabox selection

I am trying to display multiple post based off a custom metabox selection. I am currently using CMB2 as my framework to display the CMB within the backend. The selection field which has an ID of work__assign is calling all post titles from another CPT called fleet. Below is my code for displaying the CMB2 select type which then displays the titles from a post-type fleet.

ACF Date Based wp_query

I’ve been trying to order these exhibitions based on the end_date custom field created with Advanced Custom Fields. I’m not able to properly get this working. I need the most recent dates first. I need to also only get posts with the exhibition_status of past. For the life of me I can’t get this working and the below code is just the latest non working interation.
