Does anyone know how I can map Sentinel 1 SAR data to the same coordinate system as Sentinel 2 data using SNAP or a python library? My aim is to eventually crop the same subset location between the chosen S1 SAR and S2 data products.
Apply reproject from Raster tab —> Geometric Operations —> Reprojection
In snappy you could Reproject your data,
Take a look at this thread,
And in python, nice example in here, Reproject Raster Data Python

It’s possible to create Shfile, within SNAP Or other sw, and then use it to subset your area of interest in this way, from Raster tab —> Mask —> LandSeaMask
You need some preprocessing steps for example for S1 GRD data you shall apply terrain correction (orthorectification) , once it is in the same map projection as S2 you can collocate two products using raster/geometric operationc/collocation and then subset your AOI
