Difference between prepare_field and load_field

I have a staff directory on another site in my multisite. I’d like to return Staff members within my select field (as I know I can’t do this with post-object/relationship fields). But I cannot get it to work, though when I print out the query, it’s returning what I need it to.

function MemberProfilesQuery( $field ) {
    
    switch_to_blog( 8 );

    // Declare empty array
    $field['choices'] = array();
    
    $args = array(
        'post_type'         => 'staff',
        'posts_per_page'    => -1,
        'orderby'           => 'meta_value',
        'order'             => 'ASC',
        'meta_key'          => 'last_name'
    );
    
    $staffMembers = new WP_Query( $args );
    
    if( $staffMembers->have_posts() ):
    
    	while( $staffMembers->have_posts() ) : $staffMembers->the_post();
            
            $id = get_the_ID();
            $preferredName = get_field( 'preferred_name', $id );  
            $lastName = get_field( 'last_name', $id );
            $name = $lastName . ', ' . $preferredName;

            $field['choices'][$id] = $name;
    
    	endwhile;

    endif;
    
    return $field;

    wp_reset_query();
    
    restore_current_blog();
    
}

add_filter('acf/load_field/key=field_5ed9cff65f654', 'staffMemberProfilesQuery');

Any ideas as to why this wouldn’t work?

I just stumbled upon this 2 years old question searching for something else but for whom it may concern there are couple of things that can be immediately identified as weird:

1. These 2 lines will never get executed because they are after the return call:

    wp_reset_query();
    restore_current_blog();

2. The name of the function in the add_filter call is staffMemberProfilesQuery while the name of the function defined at the beginning of the code block is MemberProfilesQuery
