Those are examples of fundamental differences in thought patterns, interests, and preferences. And you are right, but a lot of that gets baked into more superficial similarities like education. But, for instance, the statement, “I want kids” can be a massively different statement from rational versus emotional reasoning.
I notice I’m sounding like Myers-Briggs, and I hadn’t thought about the validity of that.
Personally I don't think it matters a ton if you have similar interests or careers or think about things in a similar way.
What matters most is that you want the same things out of life and out of a relationship. All of those similarities don't matter one bit if one person wants kids and the other doesn't. Or one person wants to own a lot of property and the other would like to spend every spare cent travelling.
Your partner does not have to be someone you share every hobby with or do everything together with, or agree on everything with.
They do have to be someone you can build a life with.
