My go-to VPN is just wireguard to my home LAN since I only use it to protect the first hop on public Wi-Fi. If you care about your ISP knowing anything that obviously won't work

I'm interested in some discussion of the downvotes here. It solves the first problem and I stated why it wouldn't solve the second depending on what they care about. I don't personally think a VPN is a good solution for the second at all: use Tor for that imo.
