I mostly edit videos, and I make some music where "fan could speed up" vs. totally silent does make a difference. So it depends on the perspective - and it will collect more dust on the inside if it has a fan opening, so it will run hotter eventually (and need more fan).
For very light tasks - like OP mentioned - a MBP is just silent. But we all know, it's not going to stay that over the way of it's lifespan when software becomes more demanding. For sure, the air will not be as futureproof - but otoh I can still do all of those tasks on my 2009 mbp, albeit with a few gpu-glitches due to unsupported OS-updates - and a pro is double the price for virtually no speed advantages in those kind of tasks (talking about the plain M4pro) So why waste more ressources and and have another point of failure and more weight created by a fan?
The MBP could last longer, but in reality it will be cut off from software support long before doing numbers and websurfing would need those ressources.
