Print the associated categories of the current post starting with parent (with option to remove href)

Not sure why this seemingly elementary function is so difficult to perform, but I've spent a lot of time scouring the web, incorporating the suggestions and not getting the intended output.

On the single post template I would like to display the categories like this:

Parent, Child, Child

If there are no children, it will just be:

Parent

I would also like the option to remove the href. Currently I have:

<?php
  $cat = get_the_category();
  $allCats = $cat[0]->cat_ID;
  echo get_category_parents( $allCats, false, ',' ); 
?>

This doesn't work in two ways:

1) It's missing one of my 3 categories

2) It's adding a comma after the last category (there should be 3rd a category here)

The standard code:

 <?php the_category(', ')?>

prints all three categories, but I don't have the option to strip the href, and they are in this incorrect order:

Child,Parent,Child

I'm guessing there will be a super simple way to do this but it's not super simple to find online! Any help appreciated :)

Here is code snippet from WordPress that display the categories (or terms from other taxonomies) assigned to a post ordered by parent-child category relationship.This example must be used inside the loop.

$taxonomy = 'category';

// Get the term IDs assigned to post.
$post_terms = wp_get_object_terms( $post->ID, $taxonomy, array( 'fields' => 'ids' ) );

// Separator between links.
$separator = ', ';

if ( ! empty( $post_terms ) && ! is_wp_error( $post_terms ) ) {

    $term_ids = implode( ',' , $post_terms );

    $terms = wp_list_categories( array(
        'title_li' => '',
        'style'    => 'none',
        'echo'     => false,
        'taxonomy' => $taxonomy,
        'include'  => $term_ids
    ) );

    $terms = rtrim( trim( str_replace( '<br />',  $separator, $terms ) ), $separator );

    // Display post categories.
    echo  $terms;
}
