In the past I used to. It was great and my isp gave me multiple public ips but I moved and my new isp blocks port 80 so I can't anymore.
Running severs from home saved me a lot of money

What about port 443?
Normally they block most ports. So yes they will block that one too. You can still run a website without port 80 but normally it's used to redirect to 443 ass best practice.
If you buy business internet, no ports are blocked but business internet is more expensive
