Thanks for sharing this. You can add this code after vendor block like this:
{%- if settings.card_show_vendor -%}
{{- product.vendor -}}
{%- endif -%}
{{- product.variants.first.sku -}}
{{- product.title | escape -}}
{%- if settings.card_show_subtitle and product.metafields.descriptors.subtitle != blank -%}
{{ product.metafields.descriptors.subtitle }}
{%- endif -%}
