I completely understand where you're coming from, I hated my 2019 also. It was quite warm even on idle. If a external display was connected the GPU had a bug where even at idle it used a lot of power and the whole machine was hot hot hot. Any work what so ever would make the fans unpleasantly audible.
M1/M2 Macs are in a completely different league. I'm on a 16" M1 Max and it is just a dream from a noise / temperature point of view. The fans _never_ come on during normal web dev work. And the laptop is cold to the touch. I only hear the fans come on during gaming and heavy compiling.
