Books by Peter Bevelin (From Darwin to Munger etc.) or Rolf Dobelli are decent compilations. But mental models are everywhere. Taleb's books have a bunch. But start with what you have in front of you: pick one and actually apply it programmatically, then add to your repertoire one at a time.

The Wit and Wisdom of Charlie Munger is a good place to start.

Shane's mental models books are packed with a lot of random/disparate domains/insights -- He's a good aggregator there.

Thinking in Systems by Meadows.

Really, once you go down the rabbit hole, you find new threads to pull. That's kind of the fun of it
