Since even Rome wasn't built in a day, my first choice is NMEA, but I am
open to anything on higher level to come second.

What about iio?

It is quite flexible and extensible and GNSS coordinates are a not very
different from accelerometer, gyroscope or compass data as all of them
describe the position and orientation, maybe speed of the device these
things are built into (at least for mobile devices).
