Well I think I finally figured out why these boxes were ever made in the first place: the only thing that has the ids that are in the metaboxes file is an old theme that isn’t in use anymore, so I believe it is fully deprecated and I’m ready to wash my hands of it. Again, thank you very much, you pointed me in directions I never would’ve looked and this would’ve taken me days of frustration otherwise. I already typed out everything below before I figured that out though so if you’re curious:

Line 40 is $meta_boxes->add_field( array( and for context, below is how the first few sections of metaboxes.php are set up. I suspect that, probably among other things, the ‘fields’ => array is wrong because I don’t see that anywhere in the guides; I’m guessing it was done this way to group them together but I can’t make heads or tails of how to change it.

add_filter( 'cmb2_meta_boxes' , 'be_metaboxes' );
/**
 * Create Metaboxes
 * @since 1.0.0
 * @link http://www.billerickson.net/wordpress-metaboxes/
 */

function be_metaboxes( $meta_boxes ) {

	$meta_boxes->add_field( array(
		'id' => 'product-information',
		'title' => 'Product Information',
		'object_types' => array( 'product' ),
		'context' => 'normal',
		'priority' => 'high',
		'show_names' => true,
		'fields' => array(
			array(
				'name' => 'The Details',
				'desc' => '',
				'id' => 'be_product_details',
				'type' => 'wysiwyg',
				'options' => array(
					'textarea_rows' => 5,
				)
			),
			array(
				'name' => 'The Fit',
				'desc' => '',
				'id' => 'be_product_fit',
				'type' => 'wysiwyg',
				'options' => array(
					'textarea_rows' => 5,

		)
	));

				'desc' => 'Used on category and related post listings. If not provided, defaults to Summary from Product Information.',
				'id' => 'be_archive_desc',
				'type' => 'wysiwyg',
				'options' => array(
					'textarea_rows' => 2,
				),
			),

		)
	));

Yep you were right, there was a metaboxes.php file that said add_filter( 'cmb_meta_boxes' , 'be_metaboxes' ); and then a bunch of arrays. I deleted the file and it removed some fields, but I don’t think they’re even used for anything. If I’m wrong, I guess I’ll be back another day because I tried everything I could think to make the metaboxes.php work with CMB2 but it only made things worse. Thank you for your help!
