Hi,
I´m quite sure that any FPGA and FPGA board with suitable signal voltage levels can be used.
Sample/control isn´t a complex task for an FPGA.
But for sure in detail it depends on what the FPGA should do, how to process the data, how much RAM, what speed and what timing...and so on. Nobody knows better than you.
But you say "electrical power data acquisition". So why use bare ADCs, why not use dediccated energy metering devices? They do a lof of data processing for you.

Btw: "ASAP!!!" often is counter-productive when you ask for free assistance. Nobody want to get stressed .. for no paid jobs.
