Thanks all.I activated `# systemctl enable fstrim.timer` (thanks Linux-Fan).
You're welcome :)
But I do not think my issue is trim related after all. I have always a lot of I/O activities from jdb2 even just after booting and even when the computer is doing nothing for hours.Here is an extended log of iotop where you can see jdb2 anormal activities: https://pastebin.com/eyGcGdUz
According to that, a lot of firefox-esr and dpkg and some thunderbird processes are active. Is there a high intensity of I/O operations when all Firefox, Thunderbird instances and system upgrades are closed?
When testing with iotop here, options `-d 10 -P` seemed to help getting a steadier and less cluttered view. Still, filtering your iotop output for Firefox, Thunderbird and DPKG respectively seems to be quite revealing:

So there are incredible amounts of data being read by Firefox (Gigabytes in
a few minutes)? Does this load reflect in atop or iotop's summarizing lines
at the begin of the respective screens?

Thunderbird seems to write a lot here. This would average at ~18 MiB/s of writing
and hence explain why the SSD is loaded continuously. Again: Does it match the
data reported by atop? [I am not experienced in reading iotop output, hence
I might interpret the data wrongly].
By comparison, dpkg looks rather harmless:
| $ grep dpkg eyGcGdUz | grep -E '[0-9]{4,}.[0-9]{2} K/s'
| 10:38:25 4506 be/4 root 0.00 K/s 4553.67 K/s 0.00 % 0.26 % dpkg

--status-fd 23 --configure --pending
This would explain that you are seeing slow progress...
