I don't know if looking at Europe or Asia makes sense for american planners. I think a more reasonable and more politically palatable target for many US metros would be to look more like Australia, at least for land use around suburban trains. A random example:

Most of Sydney, Melbourne or Brisbane are single-family sprawled (and further sprawling) metropolis. But at least the stations of their frequent all-day electric suburban trains are surrounded by shops, even in areas very far from the city center

Even when bigger retail box/mall with parking lot are built, they are better integrated with the train station. At least one can reach it by train. Park&Ride is limited to end-of-line stations at the fringe of the city, to capture distant rural commuters

It is not some hyper-marketed modern planning buzzword (TOD, urban village, etc.), it's simply the replica of the post 1920s train-based suburbanization the Australians copy-pasted from England, just replacing terraced houses with a more "local" bungalow style house.

Maybe it's not perfect, but apparently it worked much better in keeping the centrality of trains in the neighborhood structure and landscape to the present day. Transit share is not very high compared to Europe or Asia, but is way higher than most American cities

I kind of appreciate the plain but powerful logic behind the structure of this Aussie train suburbs, that is not so different from what you find in the train suburbs of Tokyo. There is not much theory behind it, nor complicate data analysis, only a pragmatic approach to planning

Yet, we spend years in planning schools teaching theories and what theorists that never actually planned anything in their whole career think about what cities are and how they should be. I'de rather prefer more history of actual planning (how things were effectively done)

Or simply send students spend hours on google maps*** (or better, on the ground) to see how cities really are and then figure what they can learn form the existing development patterns around the world.

***here, I'm shamelessly justifying one of my guilty pleasures...

P.s. this is a sort of follow-up of a morning thought about the 15' minutes neighborhood, the we have probably already already invented... https://twitter.com/ChittiMarco/status/1287782128176988173?s=20
