Any doctor will tell you that breathing anything other than air is harmful. Vaping is far and away less harmful than cigarettes, and when used for their intended purpose (smoking cessation), they are absolutely the "healthier" option.
I pay for one domain name in Cloudflare (e.g. awesomedomain.com), and have a single "A" record pointing to the public IP of my server, and a single "CNAME" record with a value of * that points to awesomedomain.com.
That way, any subdomain gets directed to the server, and then you setup Nginx Proxy Manager to listen for certain subdomains and where to proxy them. No need to manage any further DNS records in Cloudflare, and any changes made on the proxy don't need any wait time for DNS records to propagate.
Nginx Proxy Manager also handles automatic SSL certs through Let's Encrypt - I really can't recommend it enough.
I highly recommend setting up Nginx Proxy Manager and using it as a reverse proxy.
I have lots of services, but using a reverse proxy means I only have to expose 2 ports (80 & 443) and then I can serve whatever I want, like Plex, over https without a relay.
"Smart TVs" usually suck as the manufacturers tend to put in the cheapest internals that have very little future proofing/longevity.
You're going to be infinitely better off getting some kind of android TV box (the ONN 4k from Walmart runs Google TV and it's usually around $20) and just using the "Smart TV" as a display.
They reduced the free option from 5 nodes to 3 a while back. Looks like only the people who had the 5 node license received that email.
