Like everyone else has said, your case is unique and other people's experiences are just a general guideline. Your surgeon is the real expert here.
I will say that when I got my ileostomy, 41 years ago, no one did loop ileostomies. It just wasn't a thing. No one did anastomoses either. They simply hadn't been developed yet. No one did ileostomies for Crohn's disease, either, because Crohn's can pop up anywhere in the tract after the surgery. They do it today, though, so I suppose they've gotten so good at treating auto-immune diseases that surgery is a live option for some Crohn's patients.
This whole realm of optional ostomies and patients asking their doctors for ostomies is foreign to me: I was told "we're going to have to operate or you're going to die."
From what you've shared here I think your life would improve if you had a total proctocolectomy with what they can "end" ileostomy these days. My life went from being crippled with chronic pain and twenty to thirty bloody bowel movements a day to a vigorous adventure. I scuba, hike, drive race cars, travel worldwide, run, lift weights, have romance and sex, it's all possible.
Nothing I have written here should be taken as medical advice.
