I don’t know about the US but here I can’t pay in the supermarket with stock or buy a new appliance...

Vesting is monthly (for the FAANGs I'm familiar with), you can even set it on auto sale to automatically sell your shares as they vest and just take the cash every month if you never want to see stocks. I feel like I shouldn't have to explain that publicly traded stock is highly convertible for cash!

Once they vest, you can sell them in the market.

Vesting period varies. The whole point of stock grants is that you have some what of a skin in the game.
