How do people feel about the Macbook Pro M3's with only 8gb ram. Need to replace my personal Mac (10 years old!) and budgets tight to get the top end. Need to do some coding on it, main concern I guess would be running Lando / dDev and Docker. Could also look at the Airs but no fan worries me.

I’ve been using an M1 Air for 3 years for work although I went for more ram. No problems with overheating, ever. If you’re compiling a lot & don’t need tea breaks then a pro is probably a better bet, but if you’re doing a range of tasks that might be ram hungry an air with more ram could be a better
