So I wanted to play my FFXII after so many years and it seems like this is one of those games that randomly crashes on PCSX 2.
Anyone has any idea what I could do to fix the issue?

yeah its very simple.Just search on google and youtube pcsx2 final fantasy xii settings and you'll get what you want easily

Runs better on the actual hardware it was meant to be played on (PS2/PS4), than an emulator.

Yes, I'm speaking from personal playtesting.
