I have used Linux to a limited extent for some years. Only more recently have I put more effort into trying to transition to it. I personally have a drive that has Linux Fedora on it. I customized it in a way that it resembles fairly closely to Windows 7 with its Aero theming and using the Windows logo from back then (ironically enough on a Linux OS).
For anyone more knowledgeable than me, correct me where I am incorrect. But, from what I understand, while there are many different types of Linux distributions, there are three main categories of them:
Debian-based: The most stable. Most user-friendly.
Fedora: An intermediate between stability and receiving new updates and features, customizability.
Arch: Tends to gets new updates and features the most quickly, most customizable. But is decidedly for more advanced users who are able to tinker with the OS.
Others: Not based on any of the three above. More niche.
So, for new Linux users, Debian-based distributions are the safest, which include the following:
Ubuntu
Mint
Pop!_OS
Zorin OS
For a Windows user who is new to Linux, I would probably recommend to you Linux Mint, at least to try using Linux. If the idea of using the Terminal is unappealing to you, I do not think you actually ever need to use it for at least Linux Mint. To learn how to use it would be rather useful, but I think you can stay using the GUI for a long while. I expect that there will be an extent to which you will need to tinker with things even with the more user-friendly Linux distributions, but I am reminded of someone who pointed out how, for instance, it is not necessarily the case that Windows is easy to use, but that people have simply gotten used to navigating around more unintuitive things about Windows.
One major concern about transitioning to Linux, regardless of which distribution you choose, is whether you can still do the things you need to do on a computer with Linux. Are you able to switch to open-source alternatives (if they exist), or are you specifically bound to certain software that only work on Windows?
I would recommend at least trying Linux Mint, whether on a virtual machine, a spare computer, or at least a spare solid state or hard drive. Some people recommended partition your existing drive, but I have heard of some experiencing problems booting into a system that way. I would more opt for a sacrificial computer or drive, so that your existing data is at least still safe (or at least this is my mentality anyway).
The following video explains some basic aspects of Linux, as well as giving recommendations to new users. Linux may take time to learn, but one big positive is that you have control over your computer.
Also: beware of anyone suggesting to you to type in the command
or something similar, as it deletes all of your data.
