Based on your requirements and setup involving 17 users frequently copying files over gigabit Ethernet, both the Synology DS1522+ and DS1821+ could be suitable upgrades from your current QNAP TS-431K. However, considering your need for SSD caching abilities, the DS1821+ might be the better solution due to its higher scalability and expandability options. You can indeed run a 2TB or 4TB NVMe cache for each individual partition, and for your scenario, employing a read/write cache could be more beneficial for accessing the most recent files quickly. Alternatively, you could allocate the NVMe SSDs for BTRFs indexing to enhance file system performance. Given your specific requirements and preferences, the DS1821+ seems like a promising option with its robust features and potential for accommodating your growing business needs.
