I’d let the home server connect to the VPN on the VPS so there’s a direct tunnel between the VPS and the home server. And the router is pretty much irrelevant. You can of course choose to terminate it on the router as well, bus as you said, that requires either a second forwarding. Or the entire home network to be bridged or routed.

I think I get those emails twice a year. And it’s usually same price and double storage for the VPSes. Can recommend netcup.de as well. They used to be a bit cheaper than today, but I guess every hoster increased price within the last year.
