How to programmatically implement nested JSON-LD Schema for a biography database in WordPress?

I am working on a custom WordPress implementation for a celebrity biography site. I need to generate SEO-friendly JSON-LD markup dynamically for each post.

Specifically, I am struggling with the PHP logic to nest Person schema with Financial assets (to show net worth data) and Event schema (for career milestones). Here is a snippet of how I am currently hooking into wp_head:

add_action('wp_head', function() { // Logic to fetch ACF fields for biography data // How to correctly nest "Net Worth" as a property within "Person"? });

My question is: What is the most efficient way to structure this nested JSON-LD to ensure it's valid according to Schema.org standards while maintaining site performance? Is it better to use a single array and json_encode it, or are there specific WordPress plugins/hooks that handle complex nested entities better?
