Debian Stable as base OS, then activate unstable repos in a sandbox/container. Maybe even Distrobox for newer Apps.

How about miniPaint? Its mostly in JS.

Maybe Piwigo: https://github.com/Piwigo/Piwigo

Not Fedora, but MX Linux and Antix are good for persistent installation on usb-sticks. See here: https://antixlinux.com/the-most-extensive-live-usb-on-the-planet/

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

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
https://www.zdnet.com/article/linus-torvalds-and-others-on-linuxs-systemd/

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.

yes its warsow with bugfixes. They renamed it to avoid legal issues.

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.

How about Profiles and Community Achievements? Something like Retroachievements?

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
