OpenBSD uses LibreSSL in base, but they provide OpenSSL ports/packages, including for OpenSSL 3: https://openports.se/security/openssl/3.0 https://openports.se/security/openssl/3.0 I don't know if any other ports use it; they try to make them work with LibreSSL, but maybe a few ports use OpenSSL 3.
