Basically, /bin are standard binary files to be found on all distros, whilst /usr/bin can vary between distros, but seldom does in fact - there used to be an /opt directory which was originally for added programs, but not much used.

Also, /sbin are standard system binaries, whilst /usr/sbin could vary, but again seldom does.

Most additional software these days is for graphical desktops, & get placed in /usr/X11R6/bin

Maybe, change system language, then use setxkbmap &/or loadkeys for your keyboard?

Are the dates of these the same(?).

I always turn all that stuff off!

I use desktops, & it has always annoyed, having these set on installing from 'live'.

Luit only needed for translating language sets.

Sudo is an 'extra', as the O/S works without it; main use is on desktop systems; the 'basic' minimum install is for those who know exactly the software that they need, usually administrators on/of networks.

(Reason for the net install iso.)

Daedalus hasn't been officially released yet,& I think I read that that is the reason, as they haven't yet been set up....

Sorry, we must have been typing at the same time.....

If you don't want to carry a 2.5" USB disk drive, you might like to try using an M2 SSD in an external USB case (approx 3.75" x 1.5" x 0.25") & more reliable than a pendrive.

With regards to setting up disks, I just use fdisk on the command line.

Good to know that you have had good experiences with generic 128GB pendrives, as I have just ordered 3x to try out with/on my thin client desktops.

If they've not been used in nearly 3 years, I'd just delete them - or copy/move them to external media, if you are unsure.

Creating a Ventoy pendrive is easy, just click on the version of your computer, then copy/paste distros to the pendrive....

Not all distros work under Ventoy, but it has been tested with a few hundred Linux distros.

It's a handy tool for trying 'live' distros in particular....

Chimera/chimaera - I just knew that O/S would cause problems!

You only need your actual/personal data, so use a 'live' Linux pendrive to copy it to a USB drive, (formatted as NTFS would probably be best, for re use/re installing by/to Windows partition.

I've used both RaspiOS & Devuan ARM on my Raspberry Pi computers, they work well - I've yet to run any BSD successfully on them, it seems to be a more complex installation process - I'll get around to it one day though, as some do use BSD on RPi.
