This is going to be a difficult topic. I hope everybody will note the careful use of "on average" and "tend" that are in the following.
Men and women are different. The differences are average differences. Individuals can show a huge variety of characteristics over a huge range. But on average, there is a difference.
Weinsberg and DeYoung in 2011 studied the big 5 traits and in particular Gender Differences in Personality across the Ten Aspects of the Big Five. They concluded that women tend to score higher on Extraversion, Agreeableness, and Neuroticism than men.
The difference is about one standard deviation. What does it mean? It means that if you guessed that, between a randomly selected man and woman, the woman would be more agreeable, on average you would be right about 60 percent of the time. Where it begins to matter is the extremes. If you found somebody at the extreme of disagreeable, it would be much more likely to be a man.
Does it mean you have to make women "like that?" OF COURSE NOT! The range individuals display in these characteristics is much larger than the difference between the average of men and women. Notice the word "tend." You can certainly play with these characteristics. And a character with a feature "from the other column" can be quite interesting. But, you should do it with awareness.
Just one example: conversations among women are more likely (note that, not "are always") to be about sharing and validation, where men are more likely to be transmitting information and problem solving. This is the common even cliché thing of conversational difficulty between a man and a woman. She shares her problems. He offers possible solutions. She is upset that he "wants to fix her" when what she wants is to share. He is upset that she does not want solutions. They are both upset. This conversation template gets filled in very frequently.
There are many "trope" features of conversations between men and women. From men being more likely to want to compete (the "that's nothing" trope), to men never understanding why women care about the toilet seat. (It's because they go to the bathroom without turning on the light.) Such tropes can be shortcuts to establish things. But they can also be incredibly stale and cliché.
What you absolutely should not do is make all your characters sound the same. (Unless it's a science fiction story about clones or some such.) You should find ways to make your characters stand out in your reader's minds. You want to make them like the characters you want them to like, and dislike the ones you want them to dislike. You want them to have characteristics that drive the story in the direction you want it to go. Otherwise you get a lot of walk-ons that nobody remembers or cares about.
