It depends upon your unique situation.
For example, the Abundance and Prosperity mandala can help draw more abundance into your life.
The Draw Luck and St Michael mandalas may also help reduce resistance to positive changes related abundance and prosperity, or improve your life in other areas which may be related to your circumstances.
Some may prefer one mandala over another, depending upon what best suits them and their circumstances. So perhaps experiment and see what feels best suited to you.
You might also consider creating the free Lucky Field item on the forum here, along with listening to the Attract Wealth, Prosperity and Abundance and A Life of Magical Abundance audios and using the Wealth sigil from the Energetic Addendum Est book on Patreon.
The Lucky Field item will improve your luck and can be worn together with the Abundance and Prosperity mandala, or any mandala you choose.
Also, the Bountiful Harvest album (on YouTube or other music websites, official field descriptions here) is an album meant to help specifically with wealth and abundance.
Best of luck!
