ProtonVPN can be the best bang for your back if you are thinking on buying a Proton Unlimited plan, which is basically a Google Suite alternative.

I don’t know which VPN is the best all by itself, I just wanted to mention that if it’s relevant for you.

The ones I use and suggest are ProtonVPN and Windscribe. Windscribe is free (with a limit of 10gb/month) with paid versions and is open source, it’s one of the only trusted free VPNs. ProtonVPN is free and unlimited but you can’t choose location. If you’re willing to pay, MullvadVPN is, from what I hear, the best of the best. I don’t believe any of these are blocked in North Macedonia, so you should be able to download them.
