Why is it better to have less software? I hope you're not arguing based
on the free space on a desktop computer's SSD/HDD. It's a good idea not
to run 100 unnecessary services, and since Ubuntu enables services for
ease of use by default, I usually disable them right after installing
software.

No, not on my rolling release Arch Linux installation, which has been
running daily for over 13 years and where things can easily accumulate,
nor on Ubuntu variants, where there is absolutely no possibility of much
accumulating.

Only remove software that you will absolutely never need again. You must
do this because no script can read your mind. Don't do this regularly,
only from time to time. Don't remove log files lightly.

Get an inexpensive SSD with plenty of free space if storage space is an
issue.

Check whether you want all services and background processes to start
automatically and disable anything that is not necessary.

"Bleach" sounds a bit like removing traces from a crime scene. This is
not usually used to clean the bookshelf. For me, a desktop computer is
more like a bookshelf that you dust from time to time and from which you
very rarely remove a book forever. And log files are like diaries, which
are not usually written to tear memories out of them.
