Not OP, but I’ve dabbled in nRF91 recently and found that once your application starts doing anything interesting (MCUboot, OTA, softSIM, etc.) the code size explodes. It is particularly difficult to keep TFM down to a manageable size. 1 MB of flash really doesn’t go that far these days.
Years ago I worked on the nRF52 series with the “old” SDK and felt I had much greater control. I understood the build system. Maybe I’m just grumpy and don’t like change…
That's a Zephyr thing. Same on STM32, add an otherwise trivial driver for some peripheral that has a bunch of dependencies, and then your codesize explodes by 60KB.
