With the recent windows 10 EoL news, I was able to move my dad over to Linux mint. But he does a lot of finance stuff. Long ago, Linux had a belief that desktop Linux are not the primary target for crackers but I don’t believe that true anymore since it’s getting significantly popular lately like Europe government migration over to Linux and Libreoffice.
My question would be , given my dad is just as careful on Linux as he has been on windows, would it be fine to do finance like banking and trading (not the fastest kind )?
If not, what would be your distro of choice for that? Even browsers (I installed Firefox and Edge from Microsoft website deb file)
If you’re picking a distro for someone else I would not recommend a small project distro or something incredibly niche 😅
Any of the big projects should be decent. Fedora, maybe fedora silverblue or whatever their imutable variant is called, opensuse, Mint, Ubuntu, debian. (Personally I don’t like some of the choices Ubuntu makes but it may still be a very good option for less technical folks)
Others can tell you which of those have the best security defaults, but to be honest it doesn’t sound like you actually have particularly exceptional security needs relative to what any distro will provide. I’d prioritize something stable and user friendly- which, again, your best bet is NOT picking a niche small project or something most people have never heard of
