Getting Mac Air m2/m3/m4 is it good [D]

So want to switch to macbook after running epochs on my run down vivobook which still works pretty well thanks to its rtx 3050. Now my budget us nearly 80,000-1lac rupees(800-1000$) and buying it second hand is also an option. I could have asked this in any apple Reddit pages but most of my work include python programming, sql and LLM frameworks.

Also I’m a 26 passout looking for jobs thats y building projects and always posting on x.

I wanted suggestion which to buy
M2 - can buy easily
M3 - moderately flexible
M4 - can do if my father sponsors me 🥲
M5 - on a far side but can try by using offers
