One thing you could do is to configure the hostname or IP address of the
other peer with right= for the site-to-site configs, then list the
roadwarrrior config last in ipsec.conf.  Also, the selected config can
be switched later based on the identity of the other peer, so for
site-to-site configs you can configure rightid=<idofpeer> to force a
specific config for a peer.  And since the default IKE proposal includes
all supported algorithms the roadwarrior config should also work for
site-to-site tunnels during the first phase if you don't configure ike=
and it allows the other peer to force a specific proposal by adding a !
at the end of its ike= line (e.g. ike=aes128-sha256-ecp256!).
