I had to look up NPM as in my head it’s NodeJS Package Manager but TIL there’s also Nginx Proxy Manager!

I like your VPN solution for a small group and actually tying it to their home network/router could make sense and further restrict attacks I have to deal with. However in my case I could be dealing with 30+ households of users and as others say I am bound to get people on mobiles complaining they can’t access it. However noted for future projects.
