For starters, you have several FreeBSD distributions that simply make it easy to install, once installed, it is a FreeBSD system as is.

- GhostBSD

- TrueOS

- MidnightBSD

- NomadBSD

Although the installation of FreeBSD is not far from the difficulty of installing Debian in text mode.

Besides, the official documentation of FreeBSD is much better than that of any Linux distribution, so I recommend that if you dare to start directly with FreeBSD.
