Let’s look at important things here –
Moon - Moon represents Mind, Emotions, Mother, Local Government, Peace of Mind, Home Environment, Water, Milk etc.

Scorpio - As Jyeshtha is a part of Scorpio, Scorpio sign and its representations also become important. Scorpio is the 8th sign of zodiac belt, hence it represents the things and energy related with 8th house of horoscope like Sudden Events, Secrecy, Dark World, Occult Science, Research, Inheritance, Serving Others, Taxes etc. Besides these things sign of Scorpio also represent transformation, means changing the whole nature upside down. This is one sign which is favorite of every Astrologer, because it has maximum secrets, so every astrologer gets maximum scope of researching. This is sign about which no one can tell with precision that what will happen to the planets in it, as it is sign of secrecy itself. Wherever Scorpio falls in your chart, you may have had biggest challenges in making things related with that house more stable. Scorpio is also one of those unique signs which has 2 rulers, i.e. Mars and Ketu. In Western Astrology, Pluto also co-rules Scorpio. All this makes Scorpio a chaotic sign. Scorpio consists of next set of 2 and half nakshatras, i.e. Vishakha, Anuradha and Jyeshtha.
Mercury - As Mercury rules Jyeshtha, Mercury's position and dignity is important to know about the overall functioning of any planet in Jyeshtha.
Mars-Ketu - As Mars-Ketu rules Scorpio, their position and dignity is important to know about the overall functioning of any planet in Jyeshtha/Scorpio.
Houses Involved – Also, we can’t afford to forget the houses involved as a planet can be ruling different houses and sitting in different house for every person as per ascendant and planet’s position. To know overall affect, we have to consider the houses involved as those areas of life are being impacted.
Interpretation of Moon in Jyeshtha Nakshatra – Again, Moon is in difficult position for various reasons. 1st of all, Moon is debilitated in Scorpio. Then Moon is in nakshatra of its enemy Mercury. Then Jyeshtha also spreads till Gandanta Degree between Scorpio and Sagittarius which is again a troublesome spot for gentle planets like Moon. It is also one of the Gandamool Nakshatra. So again, the results of this Moon in Jyeshtha depends a lot of upbringing a person gets from childhood and guidance given from beginning. He should be guided properly and carefully from very initial days to direct this energy towards positive things else again, this Moon can create a criminal or healer both. It can go in extremes. As always, Meditation is the only pursuit by which we can guide mind in right direction. Now, some of the traits and characteristics of Moon in Jyeshtha Nakshatra.
As Jyeshtha is represented by round talisman, it is the nakshatra which is closest to occult side of life. So, Moon in Jyeshtha Nakshatra can give inclination to occult side of life. Even otherwise, they can be excellent in any kind of research and in collecting information related to many sources. Due to mythological story, they can have a feeling of jealousy towards others, hence it also shows an unsecured mind. They can also be egoistic and would thrive only in authoritative position. At the same time, Jyeshtha Nakshatra story shows people who are good at administration and who like to have everyone having a fair opportunity at anything. They don't like any injustice towards anyone. So, these can be positive qualities of Moon in Jyeshtha. Again, their mother may have many of these traits.
Role of Mercury – Mercury placement is important to guide Moon in right direction, being Jyeshtha's lord.
Role of Mars-Ketu - Also, Mars-Ketu placement is important to guide Moon in right direction, being Scorpio lord.
Other Factors – And of course, we need to consider conjunction, aspects, house lordship, house position and dashas etc to know the exact results of Moon in Jyeshtha. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Moon in Jyeshtha can work in a chart.
