What kind of Sentinel 1 data should I download to learn how to process polarimetric operations correctly? Can I use GRD products for this?

Dear Wojciech, unfortunately, Sentinel-1 only has 2 polarizations. Quad-pol operations cannot be applied on S1 data.
Maybe this helps you:

Hh polarisation

what data are you using? In the case you downloaded Sentinel-1 (VV and VH): Polarisations cannot be generated, they are a product of sensor configuration. If no horizontal waves were emmitted by the satellite at the time of image aquisition, it is impossible to get HH information from it. Sentinel-1 (and many other SAR satellites) only operates in single or dual polarisation. For the polarimetric matrix generation you need quad-polarized data (HH/HV/VH/VV) which is acquired by only few SAR sat…
