Best way of adding Peripherals to MacBook Air M2

A hub or docking station could help a lot. There are all sorts of these, ranging from simple USB-A hubs that plug into a USB-C port, to USB-C docks, to Thunderbolt docks. Some are large enough that they are meant mostly for home/office use. Some are small and easily tossed into a good laptop bag.

If you know what your current and likely device mixes are, that could help you narrow down which hubs or docks would be most suitable for you.

An answer depends on the things you're using. Look for "MacBook Air Docking Stations".
