I second your thoughts Steve, Start with a 64bit Pi of any flavour such as the Odroid N2 or Pi 4B.
Connect to the FPGA with USB3 or i2c whatever. Also, can we make use of the GPU if there is OpenCL support? Perhaps select a Pi or other ARM SBC with OpenCL support. I'd buy one. We may not need the FPGA. Running Linux I started by Pi sojourn with a 256Mb model. Hopeless. The 4Gb SD card wore out in a day. This is why I recommend, 1Gb minimum ram. At the time, I discovered the Banana Pi had a SATA port on which I put a 250Gb SATA hard disk. No more burnt out SD cards, much much more space. And I had lots of SATA disks lying around. Laptop disks are pretty frugal on power.
