I think there are two interesting ways:

1. Either go for the Gowin FPGAs from China. You can get good boards for cheap from Ali.

2. There are FPGAs that now have a FOSS chain. They are very interesting too.

Depends on what you're wanting to do.

The OSS toolchains have matured a lot since then, with parts from Lattice being fairly well supported if you don't want to touch a vendor's tooling.

Gowin have some of the more interesting new parts which sit on a different part of the cost/feature curve. The Tang Nano boards seem fairly popular but I only have experience with far larger GW5 parts.

The newer parts from Intel/AMD have increasingly impressive hard-peripherals and internal features, but not that relevant unless you know what you want/need.
