In psychological astrology(particularly of Noel Tyl) a singleton planet can be considered very powerful, and sometimes running away with the chart.
However I am a modern(non-psychological astrologer---meaning I don't base my astrology on some kind of psycho-analystic personality theory). I use a method which takes into consideration research into chart relationships that have consistently led to events(as opposed to leading to thoughts about events).
I don't see Jupiter as particularly strong. It has a little more that half the power of your most powerful planet which is the Sun. However, what it does have is very low friction. This means that the energies of Jupiter are very easily used in your chart, and their use causes good things to happen. Because of this, you will have learned over time that they work easily and well.
Jupiter also doesn't have any issues like being in a critical degree or being out of bounds which would take it in a out of control direction. However because of its very low friction, your strongest and best aspect is the Trine between Jupiter and Uranus. This gives you enormous creativity and works to focus you toward the goals that you desire. when you combine that with your high Moon latitude, you expect to get what you want and you usually do(even if what you want sometimes even takes off without you)
.
The fact that Uranus is out of bounds, only increases the creativity to sometimes eccentric levels, and also increases your need for freedom.
I am not a proponent of one sided views of just one planet. You need to combine the Jupiter with with lots of other things to get a good appreciation of what it means for your chart as a whole.
