Templates for Long Text and Single Line Text record types

I’d love to see a way to set up a record template for the text fields (Long Text and Single Line).
Some use cases I can think of off the top of my head:

*Templates for recurring social media captions, sales responses, sales/cold-sales emails, or any inputs that need to look a certain way or go in a certain order. Long text that varies in detail but not in structure.
*Checkbox lists, sub-task lists, to-do lists, item information lists, that are required for every record.
