Yes. Solar Arcs do point to significant life changes (whether external or internal).You write very well and so Sun ruling the 3rd house(expression), Sun in 2nd(vocal chords)and Mercury in 3rd(natural home) in semi-sextile aspect to Sun points to this.
I wonder if you have a singing voice or do public speaking?
Sun contra parallels Jupiter/Neptune too-adding a tendency to never know when you are saying too much or too little in your expression. Whether you are not specific enough or too detailed etc.
Progressions as well as Transit emphasize the nature of the event. The more interaction there is between the 3 and the natal chart, the better.
The Asc 11 Cancer/Mc17 Pisces with the time and date given. With Mercury 4 Virgo (ruler of the Ic) arcing to conjunct the Ic at 17 Virgo at age 13.
Also at that time,Saturn in 4 Gem arced to square the Mc/Ic axis at that age 13 too.
I don't know whether there was a significant home life/ job status change that culminated adjustment at age 13?
The Moon in 17 Sco arced to square Mars 19 Aqua at age 2.
Moon generally rules the home life and inner world. In your chart, it rules the Asc(physical body) and so its arc to Mars at age 2 may be significant.
Jupiter 26 Sco arced to conjunct Nep Sag 0 at age 4.
Jupiter generally rules travel,religion and education(higher). In your chart it rules the 6th house (Sag) of health and wellbeing. Its arc to conjunct Nep could point to health issues.
Sometimes the solar arcs point to the environment and parents. But the more accurate the birth time the better.
Decisive moves may have Pluto there(when permanent).Solar arc Ic 17 Virgo arced to conjunct Pluto 27 at age 10.
Age 10 would be significant for complete domestic/career change according to the time on the chart
Play around with your chart planetary arcs square, conjunct or oppositions to see if there is a link.
Use traditional rulers and include modern rulers if needs be.
