How to "use" my home internet from anywhere as a VPN?

Hi everyone, I want to connect to my home internet remotely, let’s say at a university, to browse specific websites that only my home IP has access to. I’m really confused which route I should take. Should I set up a VPS or a VPN? I would really appreciate if someone could guide me or give me a link that will allow me to achieve this! Thanks!

P.S: I have a PC at home that I can have turned on 24/7. I would prefer if I don’t have to buy additional hardware such as routers orrr VPN routers.

EDIT: For anyone looking for a solution to a similar problem, just download Tailscale, login, set the desired home PC as an exit node, then install it on whatever device you want, login with the same device, and you’ll be able to use your home internet IP wherever you are as a VPN service. No need to manually set everything up yourself. Saves a lot of time and ensures you don’t mess with anything that you don’t know about!
