FLOW: tag shipping and in-store pickup BEFORE fulfillment

I’d like to automate tagging orders. During checkout, a customer chooses their fulfillment: SHIPPING or Pickup in Store, then which store. I’d like to tag each order once the order is placed, but before fulfillment. Realistically, we use these tags to sort orders by shipping, store 1, and store 2. Right now, an employee adds these tags manually. Can anyone help me set up the FLOW? I’m not sure how to begin. Shopify support suggested I begin with one of their templates: “Add order tag with the assigned fulfillment location name”, but maybe this isn’t the best way to begin?

Try Order ready to fulfill as the trigger

And the field fulfillment order / deliveryMethod / methodType
