At what point would you consider using an RTOS?
Lately I have been working with interrupt driven task frameworks on ARM Cortex-M. Basically they are using the ARM NVIC as a task scheduler. Examples for C/C++ include this one: Super Simple Tasker. For Rust there is RTIC. Both are based on similar ideas of using NVIC as scheduling engine. Very efficient resource-wise but use a somewhat different programming paradigm than traditional RTOS threads.

Take a look at the open-source Super-Simple Tasker project on GitHub. This project implements a preemptive RTOS/scheduler in the hardware of the ARM Cortex-M. It is related to such concepts and projects as:

How to deal with fast control loops in a RTOS environment?
I agree with KenaDra that such a kernel would be ideal for fast control loops and hard real-time requirements, so the OP should definitely take a look. Specifically for STM32 (ARM Cortex-M), there are some hardware implementations of such kernels that take advantage of the NVIC. An example is the SST for ARM Cortex-M. This kernel will outperform any traditional RTOS kernel on Cortex-M.
