Which MacBook should I buy?

Hello User1414,

It is ultimately up to you to decide which model would work best for all your needs. This tool can help with making a good comparison to what is available to help with your decision: Mac - Compare Models - Apple

If it's available, you can also click on the 'Ask a Specialist' link to speak with someone directly for help with purchasing.

Enjoy your day.

a base model M1 or M2 MacBook Air would suffice for such limited use. and, budget dependant, I would get more RAM versus SSD storage. the RAM and storage cannot be upgraded after the fact, but you could always use an external drive (or three) if you need more storage space. I would also recommend that you look at the link provided by Nicholas_B2 to see all available options you have.
