When one downloads data for the fundamental data providers shown below by checking their corresponding box, does that download data for every stock on earth or just the stocks in the datasets you have checked for the historical data providers above?
1 - Fundamental data providers will attempt download data for just the stocks in your DataSets. Whatever you have there will be requested by the fundamental providers you've activated.
Expect that symbols by some static providers are incompatible with certain fundamental providers. For example, most static providers would accept AAPL as valid symbol while certain fundamental provider expects XNAS:AAPL - and vice versa. (For this reason, some will fit like a glove like Morningstar's static and fundamental providers.)
So when the checkbox for a fundamental provider with its own symbology like Mornigstar is activated, keep in mind that each time you run a data update it will request data that cannot be delivered.
2 - Economic data providers (Multpl, YCharts economic, Inflation...) are not symbol specific and always download their own items regardless of how many symbols you have in the DataSets.

Also, can WealthScript get access to these fundamental stats like it could with Fidelity fundamental data? If so, where are the docs that show how?
It's the QuickRef (F11 key) that lays out the framework and the Wiki to inquire for individual provider specifics:
Home - MS123 ProvidersEach provider has its own items like "SeekingAlpha news", "[yc] dividend" or "insider transaction".

IQFeed has fundamentals, but they aren't represented here. Can WLD get access to them or has a plug-in for that never been developed?
Currently, the IQFeed provider has no support for fundamental data. Something to consider for future provider improvement.

I thought WSJ news was decommissioned. (Why is it still here?)
Somehow it wasn't removed from the binary. Perhaps I left it there for a limited time so that its users could have access to the accumulated data. Let's have it removed in v2020.08 then.
