There are some development boards like the Terasic DE10 Nano. It's sometimes a bit hard to come by because it's used by Misterfpga (a retrogaming fpga based simulator) but it's perfect to learn to develop on.

Other than that I really recommend 8bitworkshop and the Designing Video Game Hardware in Verilog. It's a great way to get started without an actual fpga board to test with.
