Debian Stable as base OS, then activate unstable repos in a sandbox/container. Maybe even Distrobox for newer Apps.
Some people use carbon foil for cars to customize their thinkpads.

A german magazine just made a video on that topic. You can activate english subtitles.

They tested a bunch of smart tvs and tv-sticks and their network activites.
They say that roku devices were the most privacy friendly tv-sticks.
And if you dont care about warranty voiding, open the tv and tape the things you dont want. Mic, cam, etc. Its probably the cheapest option
His stance on desktop security may be very hard. But his views are not far off from that of other known security researchers like Micay (Copperhead/GrapheneOS), Rutkowska (QubesOS), Matthew Garrett (Red Hat, Canonical), Solar Designer (Openwall) and others. They heavily criticize Linux and *BSDs to make us aware of all its shortcomings.
Systemd is hated by hobbyists mainly because it invalidates a lot of their hacked together wisdom ...
Maybe these people dont hate systemd but want choices for a more minimal/barebones OS. Not to gatekeep Linux but to install a more energy-efficient, lightweight Linux OS for themselves like many Alpine, Debian and Arch users do. They believe in the KISS principle. The concept that less complexity equals better security ("less is more").
not sure about the other ones, but "madaidan" (Kicksecure/Linux Hardening Guide) and Daniel Micay (Copperhead/GrapheneOS) are well known security researchers. See Daniel Micays take on Systemd:

Suckless.org's take on systemd is pretty well researched. All sources inside.
Some other critics are Ted Tso, Torvalds, Volkerding (Slackware), ... See https://en.wikipedia.org/wiki/Systemd#Reception

There are some security, privacy and stability advantages of other init systems over systemd. But for most people systemd should be fine.

Also getting encrypted dns to work with systemd is pretty tough and unreliable in my experience (with debian and opensuse). See here https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Installation-linux

This could be a problem if you are planning to use encrypted dns.
The closest thing to clean install is Ameliorated AME or Atlas OS. Check that out if you really need windows.
Use some kind of hierarchical folder-structure like the Usenet does.
Something like: unix.desktop.theming for all your desktop ricing/theming stuff, unix.lx.debian.doc for debian documentation, win.win10.winget for everything related to winget on windows 10, rl.bureau.finances for your finances, accounting, etc. ...
You can use the Browser Extension "QuickCut" to save your bookmarks in folders. Its really helpful when you work on a bigger project and have all the documentation weblinks at hand.
This. Trusty old lawnchair2. I can group all my apps in folders and have a separate menu for island/shelter apps.
Debian Stable is a solid choice as it has the best support and is a hassle-free experience. Maybe with KDE Desktop. Its the most userfriendly windows-like desktop i know of.
Optional: You can also install the MX-Tools from MX Linux to get some comfortable GUI system tools.
Just use a second phone for that proprietary stuff. So you dont have to comprise privacy/security on your main/private phone. Also a huge fan of xprivacylua to isolate proprietary apps and feed them random data.
Maybe MX linux or AntiX Linux. They are very thumb drive focused
Never tried it but there is Franz and certain plugins for Bitlbee and Pidgin Messenger
You can use posteo for 1€ a month. For more aliases look at mozmail (mozilla) or simplelogin. Or try runbox if you dont care about encryption at rest
youtube-local or yt-local with vpn. its very easy to set up
SicMu Player is good. Its available on f-droid store.
Beagleboards are great. Good Support and nice community. Nearly as good as Pi. I used BBB because it was the only open hardware SBC available in my area.
BTW: Please recommend me other good Open Hardware/Open Firmware SBCs. I am always looking for something new. Maybe for a Router or Selfmade-NAS.
Maybe try out MX Linux. It has a bunch of GUI Tools preinstalled. With MX Installer you can install Brave and even Flatpaks.
