I think the ICL, along with the court system, is at all stages is keen to resolve the matter by consent, where possible, as Sammy said. That's why even on the day of court, it's expected that negotiations occur outside the courtroom to try to reduce the number of issues in dispute.
If your family report is favourable, that may put pressure on the other party to agree to unsupervised. Whether that will satisfy you or not, I don't know. Maybe you want more. Maybe you want primary care? I don't know all the details to know. But I can tell you that the ICL in my case suggested mediation prior to a trial too. They probably feel like, from experience, it's a more productive way to negotiate than lawyers letters back and forth.
In my case, we're still a while away from the trial (6-12 months) but the ICL is clearly hoping we can avoid it. I'm not optimistic given my ex's resistance to anything that doesn't force her hand though! The trouble with mediation is that any agreement is completely by consent, with the mediators unlikely to provide any advice or pressure either side. So if the OP isn't actually willing to be reasonable, mediation will be pointless.
