It is not that critical to select a freehub type hub that enables you to remove a cassette that easily. There are small tools that can be carried on a tour. For example, cassette tools that do not need a chain whip, like this one (and there are others):

I do not like to use my frame as the wrench with that tool, so I carry a small pliers or wrench to use with it. That means needing a chain whip. But there are small work arounds for that too, example I started this thread over a decade ago:
Chain Whip for Travel
That said, I do not know the spoke lengths on my front wheel on my light touring bike because I did not build that wheel. So, when touring on that bike I do not carry spare front wheel spokes. Instead I use a Fiber Fix Emergency Spoke. Yan on this forum has ridden a long distance on a Fiber Fix and demonstrated that they work. And you do not need to remove a cassette to replace a drive side spoke if you use a Fiber Fix. Do a google search for Fiber Fix Emergency Spoke and you find lots of hits including youtube videos on how to use.
If you are worried about spoke breakage, carrying a Fiber Fix will make you less worried about spoke breakage. That said, if you do not know how to use a spoke wrench, that is a skill that you might want to learn if you have good mechanical aptitude.
