What are your most needed design assets?

Hi guys, I'm working on a tool that allows you to easily create design assets for you brand.

I've reached a stage where I'm starting to have templates made that you can then apply your brand to in 1-click, but I need your help to know what kind of assets you most frequently require.

My initial plan was to focus on social media content but I wanted to check with you guys to see what kind of assets you most frequently need to create.

So, what are your most commonly needed design assets? Is it Social media banners? Social media posts? Blog post banners? Posters? Flyers? Or something else?
