Budget gaming

Hiii I know nothing about computers, I play my games on a switch or ps5. I want to switch to gaming on a PC but don’t have a lot of money to spend on a nice one. Looking for something in the $500 CAD if that’s even possible! I play stardew valley, apex, fortnite, minecraft, etc. I would also like something that I can work from home on as well! Any help would be appreciated 🩵🩵 (monitor recommendations as well pls 😊)
