AIUI SSD over-provisioning combined with setting the discard flag in fstab(5) provides maximum performance for write intensive workloads.

Is it better than fstrim.timer mentioned in this thread?

Some years ago there was a warning on the
<https://wiki.archlinux.org/title/Solid_state_drive/NVMe>
page that Intel did not recommend continuous TRIM aka discard. Currently there are some words against discard in
<https://wiki.archlinux.org/title/Solid_state_drive#Continuous_TRIM>.

Do you have more details on this story, what was behind Intel suggestion and what has changed since that time?

As to secure erase, I have seen comments claiming that sometimes it helps to recovery performance degraded after some period of usage. I have not tried to collect details if it is related to specific models or to low end drives.
