There is https://boneworks.thunderstore.io/package/GreasedScotsman/Melon_Vault_Showdown/ which is about it when it comes to actual campaigns. Postgame wise you should check out the Hover Junkers map as there is an actual goal there. Bonelab at least is going to have proper modding support which should alleviate the lack of decent mods, maybe.
