The Seeeduino XIAO discussed in the article is a ARM M0+.
The STM32F4 is a ARM M4, a higher-end ARM. There's a lot of different chips and chip categories at this level.
Ultimately, the CPU doesn't really matter in physical projects. Mundane issues like voltage support, ADC converters and timers dominate the issues you come across.
