Thing I hare about the Air is no internal fan. The Macbook Pro has them so if you do anything intensive like AI inference you have actual airflow.

Additional point since you are considering Mac Minis. My wifes 2008 and 2010 Macbooks (the 2010 is a Pro) still turn on and run the OS just fine. I swapped the drive on the 2010 but its because she dropped it ages ago. Thats 16 years for the 2010, and 18 years for the 2008. I cant find a single Windows laptop that has lasted me this long EXCEPT the ones I installed Linux on. Something about *NIX literally saves your hardware lifespan.
