You are wrong. Linux got really easy. Check out linux mint. Hardest part is making the bootable USB. My elderly parents both like it. Installation is much easier than windows and online help is much more available also.
I'm FUCKING SICK of Windows bullshit, but Linux really scare me. My impression is that everything you do on Linux requires typing codes in the terminal, even the simplest tasks would require googling the right codes to type.
Not really you rarely 'have' to get into the terminal, it just get very convenient once you get comfortable with the architecture. Which is not really required either. My 75 yo mom love it, the most techiest thing she does is apply updates by entering her password. I need to help maybe 4 times a year..
Not really. I spend nearly all of my time on the terminal because I like it and can do things very efficiently. I grew up with DOS, so, there's extra nostalgia factor too. For a desktop/laptop, you can do everything in distros like Linux Mint without ever seeing the terminal. Hell, one can code in VSCode on Linux without ever using a terminal.
Distros like Suse or Mint don't really require the terminal. They have proper app stores and pretty much everything is in a gui menu. Including the installation process.
Try Linux in a virtual machine or on a live USB for a few days to ease into it. There's plenty of beginner friendly distros to choose from that don't require using the terminal. You could even try dual booting Linux and Windows if you decide to make the jump. I'm not going to lie and say that Linux is pure smooth sailing compared to Windows, but I can say that as a former Windows user who was terrified of Linux, after using Debian for a few days I've never booted into Windows on my main PC again
