The main thing people don't understand about saddles, is they think you are supposed to sit on them.
And sure, you do that, some. But while pedaling hard, or at least briskly, you should not have much of your body weight on that saddle. It should be about 75% on your feet.
But e bikes are ridden differently, and you will find yourself sitting a lot more. I found myself switching to a saddle with some springs built into the rear of it, and a little wider. Not too wide or I'd chafe by mile 30 or so, but not the skinny hard leather saddles I'd loved for 40 years.
Try anything, try it all, as much as you can afford to. Try shit till you find what your butt likes, for the way you ride. But if you really have butt issues on a bike, you might be loving the switch to a semi recumbent bike, with its more lawn chair type seat.
As for needing the nose, it can be lived without it. You will need to learn to countersteer more, just as you do when you switch from riding small motorcycles to a scooter, which has no tank to lean your knee on. Master countersteering, and you won't miss the nose on the saddle.
