tbh I don't remember. Give SOCKS5 a try, and if it works, great!

"socat with socks5 support (official socat release does not support socks5 proxy)"

Alright.

master branch supports it, but there's no release. build from source.

Yes, I download the source code from 'http://www.dest-unreach.org/socat/download/socat-1.8.0.3.tar.gz',
then build it on my Apple M1 pro (macOS 15.3.1 ), it works fine with socks5 proxy.

The cli:
./socat TCP-LISTEN:11111 SOCKS5:my-socks5-proxy:the-target-host:22,socksport=1081 &
ssh -p 11111 ssh-user@localhost

Also it can works together with SSH config 'ProxyCommand' option:
ProxyCommand socat - SOCKS5:my-socks5-proxy:%h:%p,socksport=1081
