Question: the way I understand it, restic forget is pretty fast – but would it suffice to bring memory consumption during restic backup down ?

No. forget only removes snapshot files. It doesn’t remove any objects.

Or would I need to do a restic prune (which I understand is really slow and would – due to locking – prevent any restic backups to run in the interim).

Yes, you would need to prune.
