I figured it out after a little work. To start, I ended up using a single callback: array($this, ‘txs_loop_callbacks’) using the same add_settings_field registration above.

(Obviously you’ll have to change the SQL, attributes, etc – just a proof of concept) add_shortcode( … Read more
This one is tricky. You need to remove a hooked function which is a member of dynamically created class instance and the usual methods like remove_action( ‘hook_name’, ‘hook_function’, priority ) and even remove_action( ‘hook_name’, array( ‘class_name’, ‘member_function’ ), priority ) won’t work.
