Hey Sebastian, thanks for the notes and kind feedback!
I've rebuilt 2 wheels in the past to replace carbon rims broken in racing incidents. Not sure if that counts! Definitely was my first time speccing out a full build and calculating spoke lengths, I think half the fun was playing around with spreadsheets and fantasizing about different builds.
I definitely agree with you that the decisions to go for 21-spokes and internal nipples are the most disagreeable and impractical choices I made. I've already had to strip my rear wheel to re-tension and true after the first 100k, and the front wheel will be next soon. No doubt a PITA, one I knowingly signed up for. I appreciate your notes on spoke hole sizes as well, good to hear a more experienced perspective on this idea.
I also appreciate your notes on the 2:1 lacing;
The decision to go for the 21-spoke build felt like a risk. At the back of my mind I still worry that I am subjecting the rear rim to bad stresses via the radially laced spokes on the disc-side. Will it be worth the 29 grams, and indeterminable, marginal CdA that I saved? Only time will tell, I suppose.
Something I noticed is that on the rear wheel, I have pretty much dead-even spoke tension across both sides. In my mind this seems desirable, no? Obviously since I'm new to this, I could be overlooking something or overstating the importance of this. On that note, something I do not like about these hubs is that on the front wheel, the radially-laced side achieve significantly higher tension than the crossed spokes. The idea that a minority of the spokes on a wheel are at a higher tension than the majority does not sit well with me, especially on a design that is supposed to "balance" spoke tensions. In retrospect, I agree that an asymmetric rim is probably the better way to do it, the asymmetric rims on my ICAN Aero 35s does a much better job balancing spoke tensions on the front wheel.
Anyways, I definitely learned a lot from the experience of building these wheels. I think next I'll build up some gravel wheels, and stick to a more traditional build

If this really is your first ever wheelbuild then you chose something with quite the steep learning curve

Ever since disc brakes, both side's spokes had to move inboard and the difference in spoke angle and tension isn't as bad as it used to be. So the advantage of 2:1 isn't really as big as it used to be.
