Hello.
When we were looking to move, I did something very similar. We still have the map on the wall. With pins.
I drew a circle from where I work with the boundary on where I lived and then another one to where I could feasibly commute. And went from there.
We did exactly this - criteria were journey time, which station we entered/left London via and last time trains. Hitchin won because of the last train being 1:30am more than any love for the place.
Naively sitting there wondering why everyone was suddenly moving down the train from the next carriage up, until the smell hits and that sets someone off in your carriage. Repeat until there are no unsullied carriages.

It's a solid plan.
