Shopping for pads for my Saab, I was surprised how hard it was to find out the friction ratings. I was looking for FF or better, but found few that published the rating or had a picture showing the rating on the pads.

The problem is the cross over. If you look at the chart, and ff pad could also be called a gg at .45. An EE pad could be called an FF pad at .35.
 
The odd thing is I've had some "lower" friction pads that felt more grippy than higher rated ones that have replaced them.

You might be overly concerned about "cross over." If the chart is accurate, the coefficient would have to be a single exact number to fall on the edge. If it's .01 either way it's a different designation.

Not odd at all. Cheap soft grippy-feel pads can fade a lot when hot, and thus get a lower rating.

This.

and I thank them for that. I've pinged a few other websites about publishing this information, either crickets or nonsense responses, listing what's already on the site and no acknowledgement that the info I'm asking for is still missing.
 
The other thing I don't completely understand is where the 90R rating comes in. This only certifies that aftermarket pads are close to OEM in performance, right?

It's is a ECE R90 regulation, which yes, coincides with OEM in performance (meeting or better), which also has country code stamping also
