Thanks! Got it working, mostly.

calling acf_form_head() is required before get_header() or before any output is created in header.php

Noted. I’ve moved this bit to the page template, called it in at right place.

// if you don’t want the above fields also saved as custom fields for the user

Regarding unset(), good call. I wish I had done this sooner, now I have hundreds of instances of orphaned post data I have to delete…

I’ve simplified the code (and also complicated it a bit). It’s solved most issues, created others.

<?php

// set ACF pre-save stuff
add_filter('acf/pre_save_post' , 'acf_create_new_user' );

function acf_create_new_user( $post_id ) {

    error_log( 'post id: ' . $post_id);

    // // exit if user already logged in, front-end form sent his ID
    // if ( $post_id != 'new' ) {

    //     error_log( 'post not new: ' . $post_id);
    //     // wp_redirect( home_url() );
    //     return $post_id;

    // }

    $field_group = acf_get_fields_by_id('302');

    //prepare basic user info
    foreach ( $field_group as $key => $value ) {

        $$value['name'] = $_POST['acf'][$value['key']];

    }

    $password           = wp_generate_password( 10, true, false );
    $username           = $candidate_email;
    $display_name       = $candidate_given_name_romaji . ' ' . $candidate_family_name_romaji;

    // check if user exists, exit if so
    if ( email_exists( $candidate_email ) ) {

        error_log( 'email exists: ' . $candidate_email );
        wp_redirect( home_url() . '/sign-up/?email_exists&user_email=' . $candidate_email );
        return $candidate_email;

    }

    // register user
    $user_id = wp_create_user( $username, $password, $candidate_email );
    error_log( 'guy just created: ' . $user_id );

    // update other user info
    wp_update_user( array(

        'ID'            => $user_id,
        'first_name'    => $candidate_given_name_romaji,
        'last_name'     => $candidate_family_name_romaji,
        'display_name'  => $display_name

    ) );

    // update other user meta, prevent creation of post data
    foreach ( $field_group as $key => $value ) {

        update_user_meta( $user_id, $value['name'], $_POST['acf'][$value['key']] );
        unset( $_POST['acf'][$value['key']] );

    }

    // redirect to login page after finish
    wp_redirect( home_url() . '/sign-in/?new_user=true&user_email=' . $candidate_email );
    return 'user_' . $user_id;

}

?>

(1) // exit if user already logged in bit has been commented out because it just grabs the ID of the page, not the post data. I can’t remember if this was working before.

(2) wp_redirect() bits are not working. I know I can add redirects to acf_form() but they’re conditional: a successful registration will go to one place and an unsuccessful one will go elsewhere.

Please note, the way I use acf_form() code has changed. I ran into some issues with calling in an entire field group and had to call in the fields one-by-one. It looks like this:

<?php

// ensures that user is not logged in
if ( is_user_logged_in() == true ) : 
    global $current_user;
    $user_id = 'user_' . $current_user->ID;
else : $user_id = 'new';
endif;

acf_form( array(
    'post_id' => $user_id,
    'form' => false,
) );

?>

Then further down the page I have a bunch of these:

<?php
acf_form( array(
    'fields' => array('some_acf_field'),
    'form' => false,
) );
?>
