Cube Reaction Wheel Help

Hi there
Wondering if some of you kind folks can help or give me some guidance
At the beginning of the year I purchased my first Mountain Bike, a Cube Reaction TM 2018 Hard Tail
This one:

Absolutely love it and suits my needs pretty well. Anyways I wanted to go Tubeless as the rims/tyres are good to go other than taping. Anyway long story short it turns out there is a crack on the join of the rear Rodi Blackjack Typ 35, 32H wheel rim. See picture attached. No luck with either Rodi or Cube in getting an answer with regards to warranty.

Anyways I like the idea of upgrading the wheel anyway however I have now idea (other than the 27.5/650) what type/size I need to be looking at and which will fit. I have also seen the word “boost” battered around but again I have no idea what this means.
SO basically could somebody tell me what type, size, axle ect ect I should be checking if I look for new wheels
Thanks

A set of these would be a decent upgrade, https://www.huntbikewheels.com/collecti ... 1070566477
Thats a good start.
So going back to basics, what I am really trying to understand is the hubs/fitting/sizes ect of the different types of wheel that I see on say ebay.
So hubs, I am assuming these are part of the wheel (the spokes are attached to the hub) so you cannot change these over easily and the wheel set will come with the hubs and thats that, you can service/clean them but unless you are discounting the spokes then you get what the wheels come with?
With regards to sizes, I am still trying to figure out what size axles I should be looking for??
