I spent long enough getting tired of routing low impact traces that I actually learned to use the autorouter.
And I mean *learned* because it was not as simple as clicking a button.
Using it right means dropping down keepouts over sensitive areas so that the autorouter knows to stay away -- you know it, but it has no way to. It means placing vias to a ground plane next to every ground pin so that it doesn't try to deal with top layer ground planes breaking. It means telling it how much to penalize a trace for being routed on the power plane layer or the ground plane layer. [and on]
It's a super useful tool -- if you are careful with it like you should be with, well, chatgpt. Give it all the information you know it needs to know, patiently and quantitatively, and sure it'll find a reasonably optimal solution. You just have to tune it as well as you tuned yourself.
[edit: and you can do it in the reverse order for nasty piles of spaghetti nets that you can't smooth out with part placement, to get hints on where you'll have to run busses later so that you leave room -- but always route the sensitive traces first]
