Pretty experienced, lifelong gamer in general but not much ARPG experience. Which difficulty do you recommend?

I've been gaming for 30+ years. I usually play any 3rd person adventure/open world/JRPG games on hard difficulty on the first attempt (assuming there is an "easy, normal, hard, very hard" scale) but I barely ever played any ARPGs. I only played Diablo 2 for 30ish hours back in the day.

I got gifted D4 for Christmas yesterday by winning a contest I thought I'd give it a shot... Which difficulty do you recommend?
