Can only try, but it will never be a complete description, not even a tip of the iceberg.
Your interest is real, but there are others who are reading, so before we begin,
God's Disclaimer:
Bhagvad Geeta 18.67 Do not reveal My Divine secret Yoga to those who are not devoted, not sincere, who are not interested in hearing about Me, or who dislike and criticize Me. (loosely translated though there is more)
-----
Without going for scripture, The One is
- Most Loving
- Most Compassionate
- Blissful
- Extremely tranquil - demonstrates pure existence. Sheer existence.
- Most Beautiful
- Very very real, simple, direct and an embodiment of Truth
- Friend of all living beings. Remember a good Father is a friend to His children. Wants what is best for them. (Someone may ask - why Father? why not Mother? He is Father, Mother, Friend, like a sibling, Most precious jewel, highest knowledge. Has no gender, and yet, is complete with both genders, i.e. is 100% masculine and 100% feminine at once).
- Lets you be. Gives you freedom within limits. On the other hand, not a blade of grass , not a bat of an eyelid, can happen without His sanction.
- Most humble and Egoless
- Selfless - has no agenda for Himself,
- Has nowhere to go, has nothing to achieve and nothing unknown/ left to know for Himself, is completely full and fulfilled in Himself.
- Only an authentic emotion, a true sentiment, a real feeling of Love will attract Him
- He knows us intricately and accurately. No one can fool Him.
- The fact that He understands us more than we do, is a gift.
- He is very sincere about the promises He makes. No one is standing there to judge Him, but He will not fail His own standards
- He is very very gentle
- Whatever He undertakes - He goes out full all the way 100%.... be it protect, love, guide, teach, mentor, nurture, support, just be there, ...
This is not even the tip of the iceberg, but this is a forum, and not a book even though we have not even touched scripture.

Part II - Read further only If you have interest.
I can point to scripture which is a Wonder that describes the Supreme Lord, a systematic introduction
- the Bhagavad Geeta is a philosophical teaching which also introduces the Nature of the Divine One.
- another beautiful exposition on the Absolute Truth - is probably "off topic" , but starts off with a beautiful shloka (verse) -- "Let us meditate on the Absolute Truth, which is the source (and cause) of the universe and became (is immanent in) [the fabric of] this universe. "
Then goes off on a roller coaster ride of truths poetically told, history, philosophy.... all towards knowledge of the Supreme Being, His interactions with the world of humans, and what humans should do.
There is more, but I will stop here. Although the Upanishads may be of more interest to you, the Wonder of God lies in the above mentioned books. Bramha sUtra bhAsya is too analytical for a beginner and will only follow if the interest level climbed the first mountain.
You are welcome to the Hinduism dir, but it can be a distraction to read conversations out of sequence. There is no need to be lost in the vastness and lose track or relevance of our Core subject.
It appears like your interest is real, and there is that earnestness.
However --- you will have to leave that Buddhism hat outside as you enter this Wonder-Route. Pre-conceived notions may not benefit much.
The Source of all Potential. Mathematically if you compute all possible concepts, thoughts, ideas, existential and phenomenal possibilities, the Source of that.
