Those XB motors are mean. They have a 6300-6400 limiter if memory serves from the 03 I had. I'd try to prop it to get close to that range for best results personally. Can you raise it up on the jack plate to try and get some more rpm before you buy other props?
in my experience prop testing the bravo xs likes to run the highest of the props you listed and the fury the deepest. That was consistent on three different hulls.

I think I could get to 1” and still be safe. Just haven’t tried it yet.
I may try run the tempest a little higher to see what happens but I don’t think 1/2” higher is going to pick up the 2-300 RPM I want to get that XB into its max performance
Maybe give the Fury 26 some more time and adjustment if you still have it. Mine is an Earl Bentz hull TR21X hp, the 26 likes 1.5 to 1.25 below pad. If the wind is right I'll bump in up a tad more. I've tried all the same props you have, and ended up with the Fury 26 full time with the 27 for the cooler weather. I don't know why, but I run the 26 much higher than most recommend. The 25 and 27 run deeper around 2.5 below pad but the 26 just performs better higher on my setup. Maybe its an odd vs even pitch physics, no idea but it's obvious from handling, speed and rpms. I have 12" hydro plate and have moved every prop through every height available.
I'm not opposed to trying that. The fury was pretty dang fast on the boat but it just couldn't quite get back into the RPM range I needed. granted, I ran it at 2.5" deep because everyone said the Furys have to run at least an inch deeper than the tempest.
