Generally ther is a lot of support for Linux on the web. There are forums you can join with people with way more experience than you have and lots of documentaiton.
I'd advise you to stick with Debian based systems as generally that is refered to more im my experience.
Also, keep in mind that just because there is support the support might be complex and beyond your ability to do.
I'd also advise to have a good back up of your Home folder (personal data) and a thumb drive ready to reinstall expecially when you first start. Or even better if you have a strong machine just use a VM. You can snapshot it easily and restore with most anything that happens beyond your control. You can also install different versions of Linux like Mint or Unbuntu or Kubuntu etc. and learn and experience it . Find what you like which destop you want (KDE, plasma etc.) for your LInux. One breaks just move to the other one. Nuke and resintall. One thing ... in general,.. installing LInux is really quick especially if you are willing to use simple commands.
sudo apt update
sudo apt upgrade
sudo apt autoclean
Debian system commands to start with. It will download everything and keep it fresh.
Also, unlike Windoze, I have some updates waiting to be installed for over a week. I CHOOSE when I want to install it not the OS. Also generally very few pop ups and interruptions. I was playing a game and Windows decided it was the perfect time to pop up a notification in the middle of my full screen game when I was right in the middle of a difficlut boss. What the fuck Microsoft? Seriously ? Nobody thought that maybe perhaps when specific types of programs are running you wouldn't pop up some bullshit notification. I couldn't access it and it was 4 times larger than the notification on my desktop without the game runniing. I had to alt tab out of the game to shut that bullshit down. Linux doesn't do that. That alone is worth the price of admission.
