My 16" MBP runs hot too - I use it for a desktop computer so it sits on a laptop cooling fan w/ tilt feature.I'm upgrading from a 16" MBP to a 13" full specced M1 Air (16GB, 2TB). The 16 is HEAVY, boringly ugly, the thing gets hot for no reason, then the fans drive me insane to cool it down and while I like the large screen size, there is nothing else I like. I miss my 12" Gold Macbook and as that's not available anymore I went for the new Air in Gold.
If I had to use it as a portable, I'd worry about the heat and battery life which as slipped to 85% over a year of use.
For travel, I use the 12" rMB 2015 and my wife uses the 12" rMB 2017 and we love it - first fanless Mac, lighter than an Air and has Retina display to boot!
13" M1 Macbook Pro - yes for work because they won't buy us anything larger....
