Extraversion and Introversion
An extravert and introvert may have some issues with one wanting the other to open up more, and one wanting the other wanting the other to give them some time alone. However, they can also be good to balance each other out, allowing the extravert to feel more comfortable introspecting, and the introvert has someone to encourage them to socialize and try new things more often.
The INFJ prefers introversion to extraversion. The INFJ is energized by alone time and will use it to help sort out their thoughts. The INFJ seeks to understand patterns and underlying meanings behind what people say and do.

Sensing and Intuition
A sensor and an intuitive will face some challenges in conversation. The Sensor lives in the concrete world of facts and senses, while the intuitive tends to wonder more about possibilities and what is not immediately recognizable. While these two types may struggle, they may also balance each other out by being able to get things done and also foresee future issues.

Thinking and Feeling
A thinker and a feeler can make for an interesting dynamic. The thinker can help sort through logical issues, but may be seen as harsh to a feeler.
