Sincerest condolences for your loss... I too have walked that path...
Predicting the death of a family member in advance is, I think, unwise;
what was significant in your first enquiry was that:
the conjunct of Jupiter/Venus was in trine to Uranus [sudden, unexpected change];
Uranus is ruler of the 5th H and trine natal Venus;
Mars was approaching the conjunct with Saturn, a significator of the father;
the conjunction formed a square with natal Mars; Saturn is ruler of the 4th H; Mars, ruler of the 8th;
Now begins the process for you to be integrating this loss, in comparison to your overall impressions of your father. Pluto transiting the 4th H shows a major 'transition' relating to family.
Saturn is the ruler of this house, in the natal chart, showing restrictions, control and authority as being influences from the father in the past. Saturn is not a serious afflictor in the chart though, thus perhaps you benefited from the structure and discipline he provided.
Pluto and Saturn are joined in the natal chart, relating to the resources you feel you received from the father [monetary or other].
Sun sq Uranus at birth: disruption or inconsistency relating to the father; possible estrangements or separation; rebellion and conflict; change and unpredictability [potentially connected with his dementia near the end].
This aspect is important as it tells us things about your own sense of Identity and Autonomy suggesting something unusual about the way you see yourself; do you have traits relating to non-conformity, resistance to authority, independence and individuality? Who was the true rebel in your relationship?
With your Sun in the 12th H the suggestion is that you may have secretive feelings about your father that may require some form of resolution, through self-analysis, etc; do you have difficulty revealing your true feelings about your father, and how he made you feel? How profoundly does this affect your life at this time?
These are things you are apt to be reflecting on during this transitional time for you.
