I've used a few rolls of the Bontrager Gel Cork tape, and it's cushy and durable...And, importantly for such wide bars, it's looong, so I think you'll get good coverage.
According to a quick Googly the bontrager tape is 203cm. Enve is 250cm and says it's good for up to 50cm bars.
Corky is a lot stretchier so I'm sure it would fit but it would be kinda thin at that point. For reference the diameter of the drops on my AGXs is 1.5 inches
I'll be interested to see what answers you get, but I was looking at what people are doing for the Crust Towel Rack as the extreme scenario. It looks like they're running mtb ESI grips or whatever in the drops, and then taping above that.
This is what I am trying currently. Wolf tooth fat paw XL donated from my fat bike and Supacaz tape that couldn't handle the curves on my FSA AGXs. Sorry if the pic is sideways.
I have Enve tape and I'm really happy with it on my gravel bike as well as my road bike. It is long enough for pretty much any bar out there. Lots of cush and a nice, understated graphic imo. Super easy to install, not a lot of stretch but seems to be holding in place really well.
so much room for activities
