Ordinarily the first option might be because it has four slots and they're
populating it with 4x 8GB, which means all the slots are filled, whereas 2x
16GB might leave two empty slots.
However this laptop has only two SODIMM slots, so it's either 1x 32 or 2x
16. Normally 2x16 would be cheaper than 1x32, but maybe it isn't for some
reason.
The Ryzen 5875U has two memory channels, so your choices are:
1x32: half the memory bandwidth, expandable to 64GB
2x16: full memory bandwidth, no expandability
Personally I'd either go with the 1x32 or 2x32 (64GB) options - can't really
see the point of paying EUR100 extra for the memory bandwidth where EUR170
will double the RAM.
Or buying the base spec (8GB) model and upgrading the RAM yourself. That
reduces the laptop price by EUR230. Locally, SODIMMs DDR4-3200 2x32GB are
GBP169.

USB-C can carry video via Displayport, so this is an external adapter to
expose a VGA or Displayport connector. Seems like the laptop also has HDMI,
so there's an adapter for that to VGA as well.
