>I do want to try games like PoR, but I'm afraid of the difficulty mixed with losing unit permanently.
PoR is genuinely a very easy game as far as FE goes. even if you lose some units you probably won't have much difficulty if you play half decently. If you're wanting to play an FE without casual mode, I'd say that's a good place to start, that or the GBA games specifically 7 and 8 because 6 gets kinda difficult.
