If you have nothing to lose, ie. if you don't play anything with anticheat or you don't use any productivity software with crazy DRM platform-locking you into Windows, do it, switch over.

The bulk of all games will run in Proton or even vanilla WINE now and the minority that's platform-locked into Windows is anything that uses kernel-level anticheat, if you only play single-player games or even virtual board games like Civilization, those will broadly work fine in WINE/Proton and even in the case of the aforementioned Civilization, those games starting from Civ5 onward even have native Linux ports, but the Windows versions tend to perform better in Proton, and as for productivity software, there's plenty of alternatives to things like Maya, Photoshop, Lightroom, or Premiere/AfterEffects to choose from that isn't platform-locked anywhere, eg. Blender as a Maya alternative, Krita or GIMP as a Photoshop alternative, RawTherapee or Darktable as a Lightroom alternative, and KdenLive or Davinci Resolve as a Premiere/AfterEffects alternative.

Oh, and as for Illustrator, you have Inkscape as an alternative, and for Paint Tool SAI, you got MyPaint as an alternative.

As for a good distro to get you started, Debian or OpenSUSE seem pretty solid for beginners, and Debian Stable at least has a backports repo for newer software, and there's also ChimeraOS if you're building your PC into a games console.

Also, if you're looking for a good Foobar2k or iTunes alternative, Fooyin is great for that, and Whipper's a good CD ripper and basically an open Exact Audio Copy clone, although it's text-based. You could also use CUERipper in WINE as another good open alternative to Exact Audio Copy, which is proprietary. CUETools will work fine in Mono as well.

What is this table from? Is it from some website?

JBL sounds like your audio gear, depends on what. Bluetooth, USB audio ot 3.5mm jack connections generally work fine without issue. (Installing PulseAudio Volume Control will help you with finer grained volume control). Some DACs that require custom Windows drivers might not work.

Gaming stuff, Steam will have you covered, Lutris, Heroic, or itch.io for non-Steam stuff. The one unintuitive thing you have to do once you log in is to go to Steam Settings and check the "Use Steam Play for All Titles". Just like that, 75% of your library that only have a Windows version will suddenly be playable and you'll hardly notice a difference: just Download then click Play, that's it (maybe a bit slower launch time).

I would recommend Firefox or Librewolf over Chrome as you have done already, but you should know that Chrome and Chromium do work on Linux FYI.

The linux ecosystem, depending on which distro you choose, has anywhere from tens of thousands to hundreds of thousands of packages. There's only select software that you can't virtualize from Windows to Linux, so you may not even be required to find alternatives.

But without listing any software at all, it's hard to tell you definitively...

Just here to recommend Zorin OS, in case Mint doesn't work out.

i didnt know Nortan Antivirus, till now

Just to chime in, since a lot of people are recommending Thunderbird as an email client. I would rather check out Betterbird. It's just smoother with more big fixes which has not been prioritized in Thunderbird.

What is JBL?

someone got oculus software to work through wine with access to hardware a while ago and they’re working on something called Oculus Ameliorated which might be simpler to get working

for a remote desktop app that also works on ios there's Rustdesk. everything else already had great suggestions in this thread

Recommend you Linux mint.

But preferably use LMDE (Linux Mint Debian Edition) instead of Mint based on Ubuntu

I think providing a list of those applications might be a first step 😉
