I don't think you can have a default value for attachment fields. You could make an automation that triggers when a record is made, but that seems a bit over-engineered. Depending on your use case, there may be another option.
As for your second question, the input needs to be a Record ID.
You've configured yours to be "Actual Trigger Time". I'm assuming this is from the Trigger action? Have a check to see if the token is listing the "Airtable Record ID" or displaying as an <ID> not <Name>.
Let me know if this helps 🙂

When I changed it to "Airtable Record ID" it didn't work as well
