market, city, town
市 centers on a place where people gather to trade and live: a market, a town, or a city. The market sense is the root idea, and the town/city meanings grow naturally from the busy marketplace at the heart of a settlement.
市 originally depicted a marketplace with a boundary or gate, later stylized into the modern form with 亠 (lid/top) over 巾 (cloth). The cloth component may reflect the stalls or banners of a market.
The top lid 亠 covers a cloth 巾, like a market stall with a canopy over the goods. Picture a busy marketplace under that canopy, which grows into a town or city.
For シ, imagine a bustling market where everyone is saying 'See! See!' as they point at the goods: 'See' -> シ, and the market is full of sights.
