Thanks John.

I ended up using https://github.com/birgire/wp-combine-queries to blend a mostly-normal author posts query with one showing posts where the user is a participant:

function author_include_when_contributor( $query ) {
    if ( !is_admin() && $query->is_main_query() && is_author() ) {
        $curauth = (get_query_var('author_name')) ? get_user_by('slug', get_query_var('author_name')) : get_userdata(get_query_var('author'));
        $authorArgs = array(
            'post_type'     =>  array('post', 'podcast', 'resources', 'video'),
            'author'        =>  $curauth->ID,
            'orderby'       =>  'post_date',
            'order'         =>  'ASC',
        );
        $contributorArgs = array(
            'post_type' => array('post', 'podcast', 'resources', 'video'),
            'meta_query' => array(
                array(
                    'key'     => 'participants',
                    'value'   => $curauth->ID,
                    'compare' => 'LIKE'
                ),
            ),
            'orderby'       =>  'post_date',
            'order'         =>  'ASC',
        );
        $query->set( 'combined_query', [        
            'args'   => [ $authorArgs, $contributorArgs ],
            'union'  => 'UNION',
        ]);
    }
    return $query;
}
add_action( 'pre_get_posts', 'author_include_when_contributor' );

I also presented the participants using this on the post:

<?php
$contributors = get_field('participants'); // array of arrays of user info
if (!empty($contributors)) {
	foreach ($contributors as $contributor)
	{ ?>
		<div class="col-md-3 col-sm-4 col-xs-2 tac contributor-badge">
			<a href="<?php echo get_author_posts_url( $contributor ); ?>">
				<div class="author-image-swap">
					<?php if ( get_field('primary_picture', 'user_' . $contributor ) ) { ?>
						<img data-object-fit src="<?php echo get_field('primary_picture', 'user_' . $contributor ); ?>" alt=""/>
					<?php } elseif (get_the_author_meta('author_profile_picture', $contributor )) { ?>
						<img data-object-fit src="<?php echo get_the_author_meta('author_profile_picture', $contributor ); ?>" alt="">
					<?php } else { ?>
						<img data-object-fit src="<?php echo get_avatar( $contributor, 512 ) ?>" alt=""/>
					<?php } ?>
					<?php if ( get_field('secondary_picture', 'user_' . $contributor ) ) { ?>
						<img data-object-fit src="<?php echo get_field('secondary_picture', 'user_' . $contributor ); ?>" alt="">
					<?php } ?>
				</div>
				<p class="large"><strong><?php echo get_the_author_meta('display_name', $contributor->ID); ?></strong></p>
				<p><em><?php echo get_field('role', 'user_' . $contributor ); ?></em></p>
			</a>
		</div>
	<?php }
}
?>
