Which floor is the best to live on in a 28-story building (help me analyze it from a Feng Shui perspective, thank you)

My experience in choosing floors when buying a property is: the floors are low in grounding, generally 6 or 8 floors are better. The higher ones are: 16th floor is better, 19th floor is better. Because people also like auspicious numbers, it will be easier to sell in the future; the same height is 26 floors. The higher it is, the more expensive it is. Economics should also be considered, whether it is for self-occupation or investment.
