Same composer (Hitoshi Sakimoto). Yasumi Matsuno, the director and scenario writer for FFT, was also one of the original directors for FF12, but he left allegedly due to health reasons. Of course, when Tanaka left a little while after FF14 1.0 failed, it was also supposedly for health reasons, which somehow didn't prevent him from being involved in a startup company immediately afterwards (and we know how much work that is), so I don't trust any announcement of health problems from SE staff. I'd love to know if Matsuno originally planned for more ties to FFT and Vagrant Story (which he also produced and directed) before he left/was forced out.
