There are very few TTS that offer larger than 6.3cf fridges. A couple Primtime Lacrosse, Open Range TTs, and maybe a couple Jayco Eagle models. So if that is a priority, then it will narrow down your choices in TTs. Many more 5ers offer 10-16cf ones.
There are many more bunkhouse TTs than 5er because that's what the market wants. Crew cab pickup 4-5 people to pull a 5er bunkhouse that sleeps 8-12 doesn't make much sense, and at $5-10k over a comparable TT. But choose a TT vs. 5er because of features, floorplan, steps, use of truck bed, etc. A premium 5th wheel receiver costs about the same as a premium WDH and both tow very well.
