Hi @jpsuarezq,
Digilent is nice in that they put examples using most of the on board devices on their site:
https://store.digilentinc.com/nexys-4-artix-7-fpga-trainer-board-limited-time-see-nexys4-ddr/
It looks like they have RTL for the RAM module:
Which is where I would start.
As for SPI vs I2C, I generally find SPI a bit easier to code up. But there are a lot fo good examples floating on Github so neither should be limiting.
