After fixing a minor glitch with some file corruption, I have resumed using NTFS3 as its speed increases are just too good to ignore. On that note, I have found that fstrim does not currently support it. Since this seems to be a known issue, I guess we’ll have to wait until an update is presented.
Here is the error message I get when running fstrim manually:
$ fstrim -v /media/VMs
fstrim: /media/VMs: the discard operation is not supported
ntfs3 has a discard mount option. That should do the trick.

This is not the preferred option for me. I do not use discard with any of my SSD partitions, using the weekly fstrim.timer via systemd instead. For now, I’ve re-enabled TRIM support for this filesystem when I’m using Windows.
I wonder why this would be required of ntfs3 for TRIM to work?
The package maintainer mentions that it is no longer necessary if you’re using the v5.15 kernel, unless you’re testing “bleeding-edge updates”.
