Building simple-to-use Customizable templates

Hi,

I am currently creating customizable templates for different needs like :
Road Maps
Instagram Stories
Pinterest pins
Slide decks
Online course etc.

Main aim is to have simple and impactful templates ,which are editable across many platforms like canva,adobe,figma,sketch,inkspace etc.

Is anyone in need of such templates for any other categories ?

Also I'll be glad to hear all your suggestions on this.

Thank you
