This is my list of recommended software for Windows. Some of them can work on Mac/Linux:

OneNote: notebook

AutoHotkey: custom hotkeys & automation

ManicTime: computer usage tracker

ShareX: screen capture & host uploading

ClipX: clipboard manager (CopyQ for advanced features)

RSIGuard: ergonomic software

f.lux: blue light filter

T-clock Redux: configurable taskbar clock

WhatPulse: keyboard/mouse usage tracker (with heatmap and rich stats)

XMeters: CPU monitor in taskbar

VLC: media player

You can use PhraseExpress to replace AutoHotkey + ClipX. It has a GUI, but is much less flexible.

If you want to make any webpage (e.g. Google Keep, Gmail) as a standalone app you can use Nativefier. I recommend you to use this command line:

nativefier --single-instance --tray start-in-tray --name "Google Keep" "https://keep.google.com" "Desktop"

Firefox

Firefox has an advantage over Chrome: its Android app supports addons. Because you can sync tabs, bookmarks and logins between devices, it’s better to use Firefox in all devices.

Recommended addons:

AutoHotKey

Recommended scripts:

Userscripts
