I too would’ve gone for a Mac mini but I can’t go without the portability of a laptop. My previous laptop was an i5 11320h with 8gb ram which was fine, I was mainly programming desktop apps, the ram would start to struggle when I was using SQL management server. CPU was never an issue. Unless you’re programming huge complex applications that would use large amounts of cpu on the end users machine, any apple silicon chip will be fine
Even if you don’t need the money that’s just completely pointless and 99% of people would benefit from an extra 1k
