Where can I find updated contents of patch version?

Can I find a web page which shows patched contents of each OS version like AAG873?

For security content, this is the best place.

I don't think all of those necessarily apply, that's why I generally like to go with Blackberry's list. Some may be different due to hardware and drivers.

Correct; for one, BlackBerry doesn't need to care about vulnerabilities in Mediatek/Nvidia/etc. components.
