Local dummy here (slightly more technical than the average user, likely far less than most people in this community) considering switching over. Checked the sidebar for any beginner's resources and looked at a few of the top posts and saw mostly Linux news and stuff meant for people already using the OS.
For my specific case, I use a Mac as my daily driver and (heresy) I am happy, but I also have a Windows computer that I am thinking of switching over to Linux. I use it to play games my Mac can't, and to run [email protected] (I do not run the community but the thing the community is about) and/or Folding at Home whenever I'm not using it to game. Some of them are Steam games, some indies not on Steam, some emulated. Little to no multiplayer games, and absolutely no multiplayer that has anticheat. I have tried running some of the Windows-exclusive games with WINE and they worked but ran extremely slowly, however that was done on my Mac so it may not represent the results of running WINE on Linux.
This one seems good: https://linuxjourney.com/
I like this, but it's mostly command-line and server related. I don't think this would teach someone as much about running desktop Linux. This seems more like something one would use if they need Linux for their job.
