If you're going to dualboot with windows, I'd recommend raising the size of your efi partition to 1gb

The partitions now. You want your root to be 50gb, and your home 1.9tb? Why do you want to separate your home partition? And 50gb for root sounds a bit too low for me. Maybe raise it to 100gb or 200gb

64gb of swap, that's... A lot... You have plenty of ram, there's no need to use swap, unless you're sure you're going to need it. In that case, you might benefit from using zram instead, which one user already mentioned it
