OP I can recommend this book . Read it myself (I consider myself to be someone who’s strength is critical thinking) and I’ve learnt interesting things. Also work with a wonderful designer who struggles with critical thinking and decision making (she’s awesome if she’s given direction and someone else makes decisions but lacking if she has to make them), and it has transformed her approach.
Decision making is a skill, just like any other so practice is what will help and this book gives you frameworks of sorts, like a template for things to consider and ask.
Hope it helps
