Calibre is great for book management. I use Thunderbird for my email/calendar since I’m on Linux and have never even though of changing. Works like a charm and it does everything I need it to.
Other software I use and recommend are:
Web browser: Firefox
Image and drawing: GIMP and Inkscapr
Plain text editing and programming: Neovim
PDF reader: Okular
Media player: VLC
Terminal: Alacritty (main terminal) and Yakuake (to have a terminal that I can easily access and then hide)
