In any case, almost definitely outside of the realm of the OPs expertise. I was just going with tires, only, but sure, can't have those without the appropriate wheels.
And yes, the tubeless setup can be heavier, and likely is when you include sealant.
You can choose whatever wheels/rims you wish. Tubular rims have a simple ring shape. Double walled clincher rims are similar, plus the added sides for the bead which much be strong enough to take the pressure in the tire plus an extra safety margin.
Single walled rims may have some weight benefit, but have largely fallen out of favor.
Thus, across all manufacturers you'll see a greater weight savings for tubular over clinchers wheels. And, there used to be discussions about "rotating weight" amplifying the differences even more.
