The nRF52832 supports both the I2C and SPI interfaces, so the main differences are speed and how many pins that are needed.
I2C only requires two pins, SCL and SDA, and allows for transfer speeds up-to 400 kbps.
SPI requires four pins, CLK, MISO, MOSI and CS, and allows for transfer speeds up-to 8 Mbps.
Thus, you should choose the interface that fits you application the best in terms of how much data and how foast you want to read it out from the sensor.
