There ought to be something in between Wiring and Linux. The problem is that the good minimal real-time operating systems are not free. QNX, VXworks, etc. are all expensive.

ESP32-based boards come with FreeRTOS built in.

Zephyr fits the description IMO.

FreeRTOS exists, and it's pretty good.

Yes if you set it up correctly, but it's very easy to set it up wrong, especially once a networking or usb stack is in the mix.

This is true for all platforms, including no OS at all, RTOSes, Linux, DOS, Windows, etc.

Fair, but there are ready-to-go Linux configurations for RPi that assume you'll do "normal" things like talk to USB devices and the network.

Additionally, Linux has available a multitude of very rich in-band debugging and logging capabilities that help you understand and mitigate common problems— whereas a bad interrupt or peripheral configuration on some microcontroller could have you banging your head again a GDB frontend or shelling out thousands for a tool like Tracealyzer to tell you what on earth is going on with it.
