Fuji makes a whole lineup of RA4 papers. Their Fujiflex Supergloss is a fabulous product with the same look as Cibachrome but easier to use, itself being standard RA4. Yes, all but one product line - the product you apparently don't like - are available in rolls only. I'm not going to press the point, since you don't have commerical RA printing in mind.
Just general information. And most of these papers do just fine with traditional optical enlargement - no need for a Lamdba or other laser printer for sake of personal printing.
Yes they do but . . . . they all fade on display. At first, it's not noticeable, then after a few years it is, and then suddenly they are washed out.
If you purchase a Colour print for display, you expect it to last. I had a print on the wall a friend made, it's so washed out it's junk, he still has the 5x4 E6 tranny so I can get a colour pigment print off it.
Even Kodachromes and Cibachromes fade. An uncle was Advertising & Marketing manager at Harrods, if one backlit image by the lifts was changed new Cibachromes were made of the others as you could spot the difference.
Having met Bob Carnie, he and I would not disagree on anything except age, he was shocked to find I was SO much younger than him
I would add months, not years 
I'm aware but the one I don't like is the only one sold as cut sheets. I just don't think it prints well in the darkroom. I actually have a small table top processor but for the short print runs I do it's hardly worth making and filling it. Inkjet is just winning all the arguments at least in my shop.
While I would rather in some ways say the opposite. inkjet/pigment prints are way better for colour.
