I agree this is a very good topic!
I have that difficult Virgo rising you mention and it does indeed cause problems. My sun is in Pisces, and my moon is in Libra.
Since Virgo and Pisces are opposites, I often appear to those who don't know me well as a very different person than I actually am, and am grossly misunderstood. I have been accused more than once of being "machine-like" because I am orderly, self-motivated, very organized, time efficient, and I get things done very fast. As an empathic Pisces, I pick up this misunderstanding, and it makes me sad. I have to remind myself that most of the people in our lives don't know us very well, so it is inevitable that they will see us as our rising sign, since that represents how we appear outwardly.
Like Mama Sunflower, I am introverted but very outgoing, which many people think is not possible, but it is. I have no secrets. I am finally learning late in life that I have to reign it in around most people though, since far too many will use my honesty and openness to hurt me. When being my naturally very outgoing self, I attract many extroverted people with a lot of baggage and no respect for boundaries, who then dump, dump, dump on the empathic Pisces until I am drained and wondering how I can diplomatically get rid of them. So, I am working on holding back more until I get a better sense of who I am dealing with. That leads into.....
The Libra moon makes me want harmony, and I tend to ignore relationship problems too long. Things that could be and should be dealt with quickly by me asserting my boundaries (always hard for empaths), usually involving someone taking advantage of me, I put up with on and on to keep the peace until they grow into huge resentments, and then I blow like a volcano, creating a permanent enemy. I am also working on this, but am trying to do it without doing it the way I see most other people do it, even my own husband, ie. by pretending people they can't stand are their good buddies just because it's easier. I do not want to be phony like that. I asked my oldest friend (an Aquarius) why she does that and she said that people you don't care about are not worth arguing with, so just pretend to agree with them and move on so you don't waste energy. To me that is going backwards in my spiritual development and I won't do it. As a Pisces, spiritual development is job number one for me in life.
One curious thing is though I have zero Taurus in my chart, I also have that craving for security you mentioned. Maybe it has more to do with a childhood spent in poverty than astrology. After all, we all have many things that make us what we are.
