I would probably use a 2 degree orb in which you would feel the effects of Mars conjunct descendant, thus these effects will likely last for a couple of years.
In addition to what you mentioned, look for progressed planets making aspects to other progressed planets, they could have strong effects. A transiting planet can also affect your life through contacting a progressed planet.
If you notice in your solar return that degree(s) are the same as your progressed planet(s) or angle(s), it will highlight the affairs of that planet and house. For example, if you have Venus at 10 degrees Gemini in your solar return and your progressed Mars is at 10 degrees Gemini, it is likely when an outer planet makes an aspect to 10 Gemini, something will happen related to those two planets. In general, the more you see a degree repeating, the more significant it becomes.
Your progressed moon is making an exact conjunction to your sun right now, this is probably your most significant progressed aspect. How do you feel it is affecting your life?
