Tested well, LGTM!

Note: I used the following to update the option:

wp option update woocommerce_onboarding_profile --format=json '{  "business_choice": "im_just_starting_my_business",  "selling_online_answer": null,  "selling_platforms": null,  "is_store_country_set": true,  "industry": [null],  "is_agree_marketing": false,  "store_email": "test@gmail.com",  "completed": true,  "is_plugins_page_skipped": true,  "partner": "square"}'

Thank you! TIL --format=json 😮
