Looking for advice and best practices for assets libraries creation

[98657751 (Max)]

Hi there, I hope everyone is doing well.
I have created over the years a decent library of high poly 3d props, example here https://www.behance.net/gallery/173457931/Retro-Game-Consoles
and here https://www.behance.net/gallery/181242099/Retro-game-consoles-2

I intend to publish these assets for the first time on the Unreal marketplace, So I was wondering if there are any guidelines, or best practices for preparing these libraries for the marketplace?

Thanks
