I have to borrow a school laptop just to do proctored exams, because their "lockdown browser" doesn't support Linux, and even if it did, it seems to do some things in kernel mode, so I don't want it on my system.
Surprisingly, most classes at my university are entirely FOSS based, aside from that one piece of software, an obscure scientific program that only one assignment used, and MATLAB (which is easily replaced by GNU Octave.)
I was speaking of the Debian "full archive" 21-DVD sets: https://www.shoplinuxonline.com/debian-full.html
But I don't know about how they package it, so it might not be a "box set" as you describe.
No distro I'm aware of still provides official box sets and CDs. Debian still provides materials for third parties to make them, though. Most of the vendors of pre-burned Linux media have also shut down, but one that seems to still exist (and offers Debian box sets) is https://www.shoplinuxonline.com/ .
Debian Stable, in my experience, can stay online for months, even over a year, with very little attention, and still work as well as you left it. You can also install RHEL or a rebuild, like AlmaLinux, RockyLinux, or Oracle Linux, as a workstation distro.
As for the device, my use case is fairly different so I'm not sure what to suggest. Maybe an Intel NUC, or a Framework laptop.
I've honestly never wrestled with Secure Boot in this way; I usually disable it if it won't let me boot my preferred kernel. From my brief online searches, enrolling your own keys is possible, but that depends on the kernel modules being signed in the first place, and carries risk of bricking devices if not done correctly. So you might just want to disable Secure Boot, or otherwise stick to kernels provided by your distribution.
You're looking at bootloaders, not kernels; you need to enroll the kernel with one of those bootloaders. Usually running sudo update-grub
while in the OS will automatically detect and add any available kernels to the default version of GRUB.
If you can't boot into the OS, you can select the kernel manually from the GRUB command line: https://www.unix-ninja.com/p/Manually_booting_the_Linux_kernel_from_GRUB
I can't object to more Jett Reno!
Wasn't screenfetch the thing neofetch was supposed to replace? Apparently it has more recent development activity (5 months ago), anyway...
I honestly have only passing knowledge of it, but my understanding is that Open Build Service is more for sharing software whose source code you are allowed to distribute. If you aren't looking to distribute at all, the solutions other users suggested might be better.
There's also a way to create an APT repository entirely on your own system, without a web server, which I haven't tried myself, but a DuckDuckGo search found this: https://help.ubuntu.com/community/Repositories/Personal
I loved the default theme, the splash screen, all of the customization options, and how lightweight it was, but it's missing some of the conveniences and polish of GNOME, KDE, or even LXQt and Xfce. Using an independent toolkit meant that none of my apps looked consistent, even after trying my best to find a theme that supported everything, and if I explored the settings beyond a surface level things started looking ancient and clunky.
Definitely underrated, and really impressive for how much they could pack into a desktop targeted at older PCs, but still missing quite a bit.
