alt Hacker NewsI don't think a regular Raspberry Pi counts as embedded, although from Embassy's documentation, there is a version of embassy for the Rapberry Pi Microcontroller.

That’s right, the keyword for embedded development would be “microcontroller”. A normal Pi is an SoC which is more akin to a traditional desktop - embassy would not be the easiest tool to use for that.
I think you’re aware of this already but for everyone else:
There’s different kinds of embedded. What traditionally was referred to as embedded is microcontrollers (e.g., 32-bit ARM Cortex M devices like the STM32 or an NXP IMX106x chip ). A configuration for a Cortex-M7 chip (that some may consider on the high end of traditional embedded) is a 600MHz clock, 1MB of RAM, and 4MB of flash memory. These run either bare metal or a real time operating system but don’t have an MMU.
These days the definition is sometimes expanded to include devices that run full fledged OSes like Linux (embedded Linux) on devices like the RPI with much more memory than an MCU.
To answer the original posters question a bit: get used to C and C++ and not using malloc() / new(), which includes a lot of the standard library.
