When I look at the diagram I think, that this would be perfect introductory FPGA project. It is interactive, so it’s fun for the designer. Plus it touches digital signal processing and interface to external components. Such project is super cool compared to all other introductions I saw before.

harder to develop and ~6x more expensive (DE10-Nano vs teensy + pico)

You can get an UPduino for $30, that's probably plenty of FPGA for a project like this.
