A distro and desktop environment recommendation for an old laptop (Read all of it, please.)

'sup? So, I am a beginner that has an old Samsung laptop from 2013 with an i3 4005U, a GeForce 710M, 500GB HDD (I will probably upgrade it to an SSD, but not for now.), 4GB 1600 MHz DDR3L RAM (the same for the HDD, will probably upgrade to 8GB some time.). It currently has Windows 10 Home but Linux is probably lighter (right?)...
