I don't think anyone is gonna have an answer to this considering you can't play it right now and also Blizzard isn't pushing updates to it until launch. There was a lot that wasn't working yet and a lot that had to be fixed still so it's all kind of speculation right now.
I can't speak for PS4, but I played for 55 hours in the beta on Xbox Series X and I found the experience to be flawless--controller wise. I had no trouble managing travel, fights, or the interface more generally. It seems a smart design and certainly a step up from D3 who's inventory interface on consoles left a lot to be desired.
I can't speak for PS4/PS5 but for PC if using a controller they will be fixing this.
