Ask HN: How do you unblock websites?

Many times when we have to use a network/ISP which blocks certain websites, there are a few ways to unblock them including proxies (in-browser) and VPNs.

Now assuming I don't belong to the crowd that exclusively uses no-log premium VPNs, what are secure options before me to, say, temporarily unblock websites?

I don't want to use one of those 1000 shady VPN apps on Google Play because God knows what they do to the device. I don't care about someone logging to which URLs I visit but proxy sites in my understanding can MITM https traffic, and also run their own ads & javascript on the browser which is last option for a security-conscious user.

So what are my options? Are there free limited VPN from trustworthy companies? (preferably OPEN ON/wireguard protocol because I wouldn't have to run their apps). Any trustworthy proxy site?
