Man, you are way too afraid dude.
It's YOUR internet connection. Who's going to ban you for opening ports and running a server? I've been doing it with comcast for 20+ years.
Maybe not all my server traffic goes through port 80 or 443, but my server is also my torrent seedbox which is high traffic and just another port. WHATEVER.
My server is just a Windows 7 PC in the living room with no monitor, no keyboard, and no mouse. Only connected power and ethernet. I remotely control it with RealVNC and it's extremely stable. The only time it goes down is a power outage because I don't use a UPS.
I use it for a website (nginx/let's encrypt), Jitsi Meet, Mumble, Ventrilo, FTP, proxy (8080), and of course torrents. Not afraid of port scans.
I use a couple of DDNS domains that I give people but I can disable the public one I give to people and change my IP any time I want.
NOT VPN. NOT Cloud. NOT VPS. NOT pay monthly to someone. You can do it all yourself for free and have been able to for decades. Quit being so scared, cell phone generation.
