FCO has a remote international (usually not for intra-europe flights) that is not too bad but I don't know of any lounges attached to it. LH usually departs from A or B and there a some small, but nice lounges in those areas.

In all honesty the international check-in is so chaotic and so filled with people that unless you arrive -- even three hours early -- you probably wouldn't have a decent amount of time to use a lounge.
