I found a new Kingston FURY Beast RGB 32GB kit with two 16GB DDR5-5600 CL40 modules for €243. Similar 2x16GB kits seem to cost closer to €500, so the low price makes me suspicious. The memory is rated for Intel XMP, and the seller is listed as Tekra. Is CL40 the main drawback, or should I be more concerned that the listing or seller may be unreliable?

This could be a listing mistake or a bad seller rather than a bargain. DDR5 prices vary, and 32GB kits can sometimes be found well below €500, especially with slower timings, but an unusually large discount deserves caution. If it is genuinely new from a reputable seller, CL40 is acceptable for a budget build; otherwise, paying a little more for a known retailer and a DDR5-6000 CL30 kit is safer.
The price is suspicious mainly because of the seller, not because CL40 RAM is worthless. Check whether it is actually sold and fulfilled by the retailer, inspect the seller's history and reviews, and confirm the exact model and return coverage. If the seller has poor feedback or the listing details look inconsistent, I would skip it even if the specifications seem legitimate.
CL40 by itself does not make the kit unusable. It has higher latency than the commonly recommended DDR5-6000 CL30 kits, but the real-world gaming difference is often only a few percent and depends on the CPU, GPU, and games. For an AM5 system, 6000 MT/s CL30 is generally the sweet spot, while 5600 CL40 is simply a slower option. I would investigate the seller and return policy much more carefully than the timings.
An X3D processor can reduce the performance gap between different memory speeds and timings, so the difference may be even harder to notice in games.
