Poles can be organized well with a pole organizer. I prefer two more poles over 10 more ground and 10 more guy-line pegs any day. In theory one would need to calculate an index per tent in terms of poles factored in with amount of ground pegs and amount of guy-line pegs to come to a conclusion. As said, I favor poles over pegs, but that is just me.
The Kapmeeuw (a beauty), a tent De Waard should continue, would have one of the best of those calculated indexes, little poles, litte ground pegs and little guy-line pegs, great height, good space. It can be satisfactory extended with a simple tarp and one more pole to gain "outside" protected living area.
The Goudplevier is really the next best "current" thing, and is often available for an attractive price. Kapmeeuw, at least of what I saw the last three years on MP, is much more seldom to get in really good shape. However, the Goudplevier only shines with full rig, so plus a serreluifel and two windscherms. In all honesty, then it is not a "one night" tent anymore. Pegs become endless.
Also in all honesty, besides a "basic" Kapmeeuw, there is little what I would dare to call a real one night tent in a 3P category. Tents becomes big fast. When people talk one night, then often really about the small De Waard tents. So with bigger kids (which you don't have) they take two small tents. If you set up a Grote Bonte Specht, it will also mainly shine with (XL) tarp. Once that is done, you also had your fun with pegs, but anyway....it does not fit your dimensions.
Conclusively, I would go for a Goudplevier just because you find it more often in excellent shape very nicely priced and then live with some small downsides vs. a Kapmeeuw. We set up our Goudplevier any day with more fun than our former Overloper
If you find a decent Kapmeeuw, I would not take any second guess.....jump on it.
