I can glean the basics just by looking at the monster stat blocks, but I'm interested in the fringe examples and where that info lies in the stat block. Having an official template would be nice.
What do you mean? Page 5 of the Bestiary has the official template for how monster stats should be formatted, I don't think you can get any more official than that.
It's not official but PF2.tools has a number of useful, well, tools.
Their monster tool seems pretty accurate as far as I can tell.
The Bestiary template is available here: https://2e.aonprd.com/Rules.aspx?ID=784.
Note that it's part of a web page, so you'll need to copy and paste it into a document if you want it on its own.
