You need to add one parameter 'checked' => true, in your code like below,

$fieldset->addField(
 'applies_to_addons',
 'checkbox',
 [
 'label' => __('Applies to Addons'),
 'name' => 'applies_to_addons',
 'data-form-part' => $this->getData('applies_to_addons'),
 'onchange' => 'this.value = this.checked ? 1 : 0;',
 'checked' => true //add this line in your each fieldset.
 ]
 );
