I used this one:

Essentially gives you Final Fantasy Mode without having to finish the game first. It sounds like it will be overwhelming but it really isn't. It's what most other games would have called Hard and let you play as a fresh start.
I also avoided using potions on top of using it but that's up to you.

See above for the mod, as for the other games, XV is supposed to be excellent but I'm not sure, only played it on PS4 myself. XIII needs a mod:

It does a few things but more notably stops UI effects from tanking your framerate no matter what hardware you have. With that installed, it's perfect. Looks amazing at stupidly high resolutions too.
There are also mods on nexus to do stuff like use cutscene models in gameplay, that probably looks great too, but I didn't personally use them.
