For restic:

1. Every backup is incremental after the first or rather restic makes no distinction because it chunks and dedups the data on the way in so if it's already in the repo it doesn't get stored twice.
2. Restic has customisable 'forget' cmd that can do whatever you want
3. Restic has filtering flags, you can use a gitignore style file also. Many people use a wrapper though like autorestic.
4. The ghost files are interesting. Restic has nothing special for this. A script that mirrored those files and wrote them all as 0 bytes which restic could then backup would be possible, this would work same for any backup tool.
5. You get that summary after every restic backup. You can also compare snapshots and mount them all to run your own analysis if you want.
6. Again if you mount a restic backup you have access to every file and snapshot taken in the repo. You could compare or diff them using usual tools.
7. There is a 'exclude-if-present' option where you can say if a file with the name of your choosing is present do not backup that dir etc

I'm a fan of restic. I'm using it for workstations and homelab servers. I have two complaints. Scheduling backups isn't integrated into the tool (but other wrapper tools like resticprofile do a great job of cooking the gap. And restoring from backup is more of a headache than I'd like.

I've been using Duplicacy. I pay for the GUI because I still struggle with CLI-only tools.

Interested to see what others suggest though.

It's not in your list but veeam has a free version and I really like it.
