the team at Radiona.org / Zagreb Makerspace has been developing an educational FPGA board ULX3S for several years. The board is fully open-source and can be programmed using open-source tool chain. ULX3S has a bunch of features and it has been used and tested in many different project. It is also being used on several universities in courses on digital electronics.
After many months of preparation, the team has successfully launched a crowdfunding campaign for the ULX3S FPGA board with ESP32 so now it is available outside educational environments. Of course, you can also make one yourself since everything is open source. :)
