Blender by a huge mile. Yes, there’s tons of other software like Linux, of course, but Blender is such a powerful, well managed, economically viable and healthy (community) project that it should be shown as an example of how Open Source should be.
My biggest hurdle with other projects is the fanboys, because many times they’re quite toxic, insulting everybody who doesn’t adore the project and don’t accept constructive criticism.
Proxmox, opnsense, fdroid, and many more on r/selfhosted (now on lemmy also) .
sunshine, moonlight ( play my games anywhere in the world, games run on my pc at home)
Firefox (the best browser against google monopoly), thunderbird (best mail client)
LineageOS, microG, Mozilla Location services, Magisk, aurora store (let me use Android without any of google tracking)
Bitwarden, Proton mail/vpn, Nextcloud (finally no gmail tracking)
Jellyfin, kodi (lets me create my own Netflix)
GNU/Linux, GNOME, KDE and host of other Linux projects. No more windows tracking. Also if you want to really know how the OS works, you should start tinkering with Linux. I expanded my knowledge base by just using Linux as daily driver.
The list just goes on and on. I am so grateful for all the open source devs that put their time in developing these tools.

LibreOffice is equal to any office software out there, and has been much more stable than OpenOffice, and works without an internet connection unlike Google Docs.
Not by importance. Obviously that would be the Linux kernel, GCC and GNU coreutils, and the Firefox web browser, among some other foundational things (code to run my desktop GUI, for example).
So, I'll say my favorite is PCSX2. Ever since they got rid of the ancient plugin architecture this emulator has been getting sooooooo much better, and it was already great! I would add other top tier emulators like Dolphin, DuckStation, SNES9X, SameBoy, and so on. I just love emulators :)
Ill throw in some obscure ones I use daily.

StemRoller. It's an AI-powered toolthat takes an mp3 and separates each instrument into its own file. Im a musician, and having access to stems like this is a game changer.

Carla is a tool for hosting VST plugins without the need for a full DAW. I primarily use Amp Simulators, and this has become a mandatory tool on any computer I use. It's also maintained by the creator of KXStudio.

Uptime Kuma is a fantastic selfhosted status page system. You can use it to track and notify you of network outages or it can scrape a url for a key word and alert you when it's found. I've heard people using the keyword feature to find out when RPI go back in stock for example.
I use it at work to keep track of our systems and their uptime as well as cloud systems we use.
