I have an post article, with a title date and the category the post is assigned to. The post is in multiple categories, but i only want to show the 'main' one its in and none of the others (for now).

How do i search through all the categories the post is assigned to and only show the one with the most posts in? Therefore giving that category the idea as the main one?

I assume cycling through get_the_category counting all the posts within all the categories assigned to this post and then picking the one with the most?

$category_main = get_the_category(); //But only the one with the more posts than the others?

if ( ! empty( $category_main ) ) {
    echo '<a href="' . esc_url( get_category_link( $category_main[0]->term_id ) ) . '">' . esc_html( $category_main[0]->name ) . '</a>';
}

Thank you for any ideas :)

get_the_category() returns an array of WP_Term objects, so you already have access to the count property - just sort the array by it and retrieve the one with the highest count:

$main_category = current( wp_list_sort( get_the_category(), [ 'count' => 'DESC' ] ) );

Check out the documentation for wp_list_sort()
