The best way to switch imo is to first to switch some of your currently installed app on windows with others that have a linux version, so you will not be entirely lost when you switch os.
For example Microsoft Office is not available on linux so maybe try libreoffice or onlyoffice, another example Photoshop doesn’t have a linux version too.
Then maybe try to familiarize with the os on a vm or on a live usb, especially on a live usb so you know what works out of the box and with your hardware.
If you want to game look for you games on protondb if they work or not, for online games instead watch areweanticheatyeat to see if the anticheat work.
Last tip is to go with a know distro not something obscure like steamos or kali linux, they are not meant to be used as daily drivers especially kali and can give you problems that will not occurre in other distro!
