And get in the habit of ejecting a mounted external drive (flash USB drive etc) or DMG image/installer (worth Googling this one but similar to mounting an ISO within Windows) before unplugging it from the Mac by either selecting the drive in Finder (Windows explorer equivalent) and either pressing eject or using the shortcut CMD + E.
One preference i do is to display mounted drives on the desktop which is a setting under (open a Finder window, click the 'Finder' menu on the top menu bar) Finder > Preferences > General, 'Show these items on the desktop'.
Considering what you'll be using the Mac for, then the experience will be fairly similar other than the odd quirk or minor difference like shortcuts, eg - Alt + Tab becomes CMD + Tab.
Personally, the two biggest pain in the rectum issues with MacOS (having to switch between Windows and MacOS daily) is the lack of built-in support for window snapping or not all windows/software/apps supporting window maximise (option/alt + click the green plus icon top-left on a window).
Rather, you have to use third-party paid apps for window snapping and you have to get comfortable with manually resizing windows and/or using full-screen (click the green plus icon, only, on a window) with multiple 'desktops' and Gestures which is all a bit clunky compared to Windows. But you get used to it.
Good luck!
