If any fediverse platform devs are interested, it appears you could request a collaboration with Facebook / Instagram to create a "Transfer Your Information" process.
This would allow users to just click a button and have their posts converted over to another platform rather than deal with the whole archive export / import.
There's already one for Wordpress and Blogroll.
