Can Law Enforcement Really Recover Files You’ve Deleted?

Bleachbit, shred (from GNU coreutils), and zerofree (if you have a way
to easily remount as read-only before and remount read-write after) are
your friends. On a mechanical drive, overwriting once with zeroes beats
not overwriting at all, though I would definitely do more than that if
there's data you really can't risk falling into the wrong hands. On an
SSD, TRIM early and TRIM often, and the drive takes care of this for you
(even on Windows, which will helpfully TRIM for you up to once per day).

Critical data doesn't have time in situations to fuck around with that wiping bullshit. You need a strong crypto filesystem when powered down, and when up, a keyboard combo rigged to blacken keys and reboot. Then cron/keyboard run whatever wiping tools inside that regularly.

If you can spare the extra overhead to run a crypto filesystem, yes, do
that. (On systems as old as my current laptop, it's barely a workable
option, and I did notice better performance when I went back to an
unencrypted filesystem. Then again, my threat model was strictly
protecting against my laptop getting stolen when out and about, less of
a concern now especially with the COVID-19 pandemic limiting the need to
take it out of the hose.) However it still can't hurt to wipe deleted
files and free space as a matter of routine privacy protection.
However, do be aware of things like encrypted filesystems complicating
data recovery in the event of software/hardware failure. Sure, maybe the
cops can't get your data, but it can bite you in the ass when Shit
Happens(tm) and as a result *you* can't get your data either.
