For the Tor Project specifically, the most up-to-date (that is, the most recently developed) are Conjure and WebTunnel.
Here is the Tor Project’s repo group for pluggable transports. And here’s the Tor Project’s anti-censorship roadmap.
I also asked roughly the same question a while ago on Matrix.
About non-Tor-Project ones: I’m not very knowledgeable in this area, but I’ve heard of v2ray and x-ui, which are resilient against active probing (like WebTunnel), I heard they’re used in Iran and China, when Snowflake and obfs4 Tor bridges don’t work.
