Depending on your experience on using Linux you have some options, also you have options depending on the base distro.
I like to use directly Debian installing from the netinstall image, but I know it should be a little bit harder if you don't have too much experience because of that I have to recommend you Ubuntu.
I don't have experience in desktop environments based on RedHat like Fedora but is a very good distro with a lot of community and support from RedHat.
In the end, you need to think about community, support, and updates, then maybe try some of them to finally decide which one is for you.
