I actually suggest getting Ventoy which is a fantastic utility that allows you to copy bootable images to a folder, and when you boot the drive you can select from the ISO/Images available on the drive. Super handy!
The Live USB may not solve all HW issues, but it's a good jumping off point.
I can't blame anyone not going the pure arch route, and choosing an Arch based distro. Besides getting my GPU working as I wanted it, running and maintaining my Arch install is no work at all at this point. With Timeshift installed, as well as the grub hook, and pacman hook, it makes it a cake to revert if something breaks.
The other advice I have for Linux is an often overlooked. When switching to Linux you can't always approach fixing a problem or operating the machine the exact same ways one would on Windows. So being flexible, and learning to change habits helps.
