I recently read on the website of a major paving manufacturer that terrace slabs should never be laid without joints (3-5mm). Unfortunately, it didn’t say why that should be the case. Maybe someone here knows? It would of course be better without all the sand, since you constantly have it on your feet.

No standing water, no carelessness during installation, expansion summer - winter
I'll see if I can find a photo. The joints are very minimal and not something to sweep out.
we also have joints, without joints a professional has to do it (I guess). It's just not such delicate work. But we also laid it on gravel and compacted the ground beforehand.
our terrace is currently being done as well - and the joints are being grouted with sand. Does it make sense to finish the top layer of the joints with [Pflasterfugenmörtel]?
The grouted sand will probably remain on the terrace during cleaning over time and may even be washed out/swept away eventually. Would [Pflasterfugenmörtel] be a sensible addition?
We have 60x40x4 terrace slabs with 3mm joints. Before laying them, I spoke on the phone with a nice lady from the manufacturer company, who then explained to me that the corners could very likely break during installation. Also, the rainwater cannot drain well without the joints, and therefore there will be wet joint edges.
Great idea with the windows in the terrace partition wall. *Thumbs up*

No, you don't. The sand stays in the joint and becomes firm. Ideally.
