Any vanilla Linux distro will work, although Ubuntu or Linux Mint will be easiest to install and have the best hardware support out of the box. The latest version of Ubuntu (and by extension Linux Mint, since it is based on Ubuntu) includes a one-click option at install time to set up FDE. The main difference between them is the default desktop environment. Ubuntu includes a DE that a lot of people don't like, although there are derivatives such as Kubuntu, Xubuntu, and Lubuntu that use a different DE by default. Linux Mint uses its own DEs. The way to choose is to read up on and look at screen shots of Unity, XFCE, LXDE, KDE, Cinnamon and Mate, and choose the one that you like. You can also boot Live CDs and test them out. Keep in mind that once installed, you can switch between any of the DEs by installing them from the software repository. It is even possible to install the Cinnamon and Mate DEs (of Linux Mint) on Ubuntu and vice versa, so it's not a choice that you should be laboring over. Any normal Linux distro will have a normal filesystem layout without the complications of Tails. You will also be able to install any software available in the repos, unlike Liberte. My other gripe with Tails and Liberte is that they are "experimental" distros at best. They have been around for less than 3 years and have one (in the case of Liberte) and maybe a handful (in the case of Tails) of developers behind them. In my experience, and judging from dozens of threads on the forum, they are buggy as hell. It would be easier for a newb to use Ubuntu and Linux Mint, which have been around for a lot longer and have more developers behind them. Once you've committed to installing one of the Ubuntu/Mint spins, it's not that hard at all. The main barrier seems to be in the cost or inconvenience of committing a whole computer for this purpose.
