It’s not uncommon for road wheelsets to have 4 or 8 more spokes in back. Ditto for all those old English 3-speeds. The rear wheel usually sees a bit more weight, and front hubs generally have wider flange spacing so front wheels can be strong with fewer spokes. But since you’re not carrying a big load, you don’t need a beefy wheel either. My vote would be for the Pacenti, but most of the rims on your list would be fine. Don’t fret about 1mm here or there on rim width.
BTW, you may not want to run tubeless, but I’ve had good experiences using tubeless-compatible rims with tubes. The snug fit at the bead seat helps tires to mount up straight without a lot of hand manipulation, and the deep well in the center provides the slack needed when mounting or dismounting.
