Web Browser: Brave (Chromium)

Terminal: Terminal (with oh-my-zsh)

IDE: VS Code

Basic Text Editor: VS Code

PDF Reader: Brave (Chromium)

Office Suite: Google Docs/Sheets etc

Calendar: Google Calendar

Video Player: VLC

Music Player: mplayer

Image manipulation: GIMP

The main things I always add are GIMP, Brave, oh-my-zsh and VLC. Getting a good/working browser does most work for me.
