Lightroom. There are lots of alternatives for editing some even FOSS but I haven’t found any usable alternative to the library of Lightroom…
Photoshop is easier to use than gimp. I don’t pay for photoshop, but if I needed something like that I would.
The Jetbrains suite of IDE’s. Particularly Jetbrains Rider. The platform ~~they are all ~~ many of them are built on is open source though, and you can get free licenses for all of their products if you are using them to develop open source software!

Yes if you’re just writing your own simple documents libreoffice/OpenOffice will work, but if you have to do anything more complex than a single page spreadsheet, text-on-white presentations, or 3 page MLA book reports… or, even worse, have to interact with documents and spreadsheets created by basically any other person on the planet, I’ve just never had a good consistent experience with any of the free options.
Disagree. Libreoffice is pretty capable for most use cases nowadays.
Compatibility is also pretty good with Microsoft formats despite Microsoft‘s best efforts.
OpenOffice is dead.
