I am using Raspberry Pi Pico and Adafruit PN532 library and I have problems reading NTAGs (213) with SPI. It only reads UID but not other content.
And after some experiments, I found out that changing the BusIO: Adafruit_SPIDevice.cpp file
uint8_t bitdelay_us = (10000000 / _freq) / 2; // was 1000000
it will start to work. Tested it with Arduino IDE 2.x and PlatformIO
