The Microchip "Icicle" came out in late 2020 with the largest FPGA in the range, made using pre-production chips. It was several years more before you could buy the chips themselves. Digikey says it's no longer manufactured and they're just running down stocks.
The BeagleV "Fire" is much cheaper ($150) and uses one of the smallest FPGA parts in the range.
GOWIN also has RISC-V FPGA SoCs (Arora V GW5AST series)
