Apt tends to store files in /var - it's possible that /var is also full.
If you repeat an apt-get update - do you have errors about needing
to rerun a configure step?
In thi situation, I might be tempted to save off any data in /home and any
options in /etc/ to configure mail and things like that and
do a reinstall with Debian 11 as a quick fix but that's a destructive
option.
apt-get clean may clear out some downloaded packages and provide some space.

When you installed, did you manually specify sizes for filesystems or
did you say "install in one encrypted LVM"?
If you did that then, effectively, /home and so on are auto-sized and LVM
is keeping track of free space. Deleting unwanted files is the only way
to reclaim space and then, perhaps resize.
There's a reason that I install into one filesystem if I can - manual sizing
and partitioning rarely works unless you have a specific use. On one machine
here I have a 7TB /srv partition deliberately because it's full of data
that I want to serve out via a webserver - in any other machine, I'd probably
have said use the whole 8TB filesystem and auto partition.
