Haven't looked at the full synastry, but just looking at the "notables" you listed, tbh, the only thing that strikes me as particularly powerful and potentially twin soul connected is the Sun Moon conjunction. I haven't observed the vertex to be that significant in relationships, unless one factors in a more whole sign type connection rather than "in orb" aspects.
But some of the more common twin soul synastry that I have noticed is Sun opposite or same Sign as the others Moon (doesn't need to be "in aspect" necessarily, but stronger and more immediate when it is). Sun opposite or same Sign as the others ASC and especially strong when the Sun is also either conjunct the ASC and/or in the 1st House or conjunct the DESC and/or in the 7th.
And when the ruler(s) of the ASC of one, and the ruler(s) of the DESC of another are conjunct or opposite in aspect and to lesser extent just in same or opposite Signs--this is another strong one.
For example, in one twin soul case, partner A's Sun/South Node conjunction is opposite Sign of partner's B's ASC and in their 7th. Partner B's Venus is conjunct partner A's Sun/South Node conjunction and in their 1st. Parnter A's ASC is conjunct partner B's Sun which is their ASC/Chart ruler.
Partner B's Moon is conjunct partner A's Saturn which is their ASC/Chart ruler and Jupiter, and partner A's Moon is opposite partner B's Moon which is their DESC ruler.
There are many other aspects and patterns, but these are some of the most notable/significant.
In another case, Partner A's ruler of Sun, 8th, and co-ruler of Moon is almost exactly conjunct partner B's ASC and opposed their Venus which rules their Moon, MC, and Pluto Signs.
Partner A's Sun is in the opposite Sign of partner B's Moon.
Partner B's Sun which is the ASC/Chart ruler is conjunct modern ruler of Partner A's DESC, Venus, and Saturn (Pisces) and in their 5th House. Co-ruler of Partner A's DESC, Venus, and Saturn is conjunct partner B's ruler of the 8th and is very closely conjunct the 5th cusp.
Partner B's Jupiter which is the ruler of their 5th and co-ruler of their 8th is almost exactly conjunct partner A's ASC and trine their Mercury/South Node conjunction where Mercury rules Partner A's ASC and MC.
The ruler of partner B's Sun and Mercury Signs and the faster moving ruler of their DESC and Venus Signs, is in partner A's 1st House and opposed their Venus Saturn conjunction which is in their (partner A's) 7th House and where Saturn rules the 5th and Neptune (ruler of DESC/Venus/Saturn) Sign, and Venus rules partner A's ASC/Chart ruler/MC ruler Sign and South Node placement. (that sounds confusing, i.e. Partner A. has Virgo Rising and Gemini MC with their Mercury in Taurus conjunct Taurus South Node).
Partner B's modern ruler of DESC and Venus is conjunct partner A's Moon, and partner A's Moon is in partner B's 4th House. Partner A's North Node is conjunct partner B's Nadir.
There is a lot more else going on, but these are some of the most notable as regards twin soul connection.
