What is the reliability of the Wake-on-LAN functionality these days? What are the issues one should take into account when using the functionality? Is the functionality somehow manufacturer-dependent? If yes, then which manufacturers are the leaders in this area? What kind of PCPC-based devices are there in the market that would support remote customer service in an unoccupied location? Is there a need to boot the PC in between customer meetings to clear the memory (because of data protection issues)? Are there any other drawbacks of this kind of set-up one should think of?

Wake-on-LAN is generally reliable when implemented correctly. Firewalls and network segmentation can impact WoL functionality. 
WoL functionality is generally standardized.Most modern motherboards and network adapters support Wake-on-LAN.Leading manufacturers of motherboards and network adapters, such as ASUS, Gigabyte, Intel, and Realtek, often provide robust support for Wake-on-LAN.
Any device that supports Wake-on-LAN can potentially be used for remote customer service. This includes desktops, workstations, and certain laptops with the necessary hardware.
Whether to boot the PC between meetings for data protection depends on the nature of the discussions and data involved. In some cases, it might be advisable to reboot to clear sensitive information from memory.

some of the cons;

Network Configuration
Power Consumption
Security - WoL packets could be intercepted, posing a security risk..
Compatibility - Older hardware
