As long as you state your boundaries sternly, or prove yourself, you can make sure they don't cross the line.
In family and friend relations, I have just told them what I won't tolerate of their behavior, and they seem to adapt to me. They can actually become helpful people to have around, once you teach them what habits you won't stand for. I have noticed that many sfjs tend to not mind taking orders and learning how to relate to you. Its harder to convince the stj, however. This is why I probably find it easier to deal with sfj. They aren't useless like some nts think, either. I have had sfjs really surprise me before. One of them help me understand something very important to me once, because they had an understanding of the situation that I couldn't grasp, as a person with very little s.
I have worked with sfj types before, and what bothered me most about them, was they they felt they needed to micromanage me. For the first little while, I will keep my mouth shut for the most part, and observe. Once I know I have the hang of it, I will then tell them how -I- am going to do things. They are usually pretty astonished by the ingenuity. Now, if you prove this to them, they will typically stand back and let you take control.
I really don't find it any harder to deal with sfj than any other type. People are all different, and have their own unique quirks anyway.. and any type can have something to offer. You just have to learn to speak their language a bit.
One of my best friends was a 62 yr old esfj. Unlikely pair, us, I know.. but we got along swimmingly. She actually had great taste in novels - David Sedaris for example, and she had lots of knowledge of gardening which I am also into. She also had a lot of life experience, and had encountered introverted NT women in the past, so she just kind of knew how to treat me. : )
