I had similar requirements and fell upon mesh central. To keep it secure on web I have it hidden behind cloudflare tunnel and an access policy.

Bonus points it even supports mobile devices if you need to help your mum with those too.

Another one I was a fan of was level RMM if you can stay below the 10 device limit it’s completely free - all hosted on their cloud. I have too many children so had to switch from level.

I just sent a ddos attack to his ip. In an unrelated event my doorbell camera has stopped working?

It was Plex that did the IP range ban because people were selling access to their boxes.

There are two types connection in this scenario

1. Direct - no additional cost to Plex, using the port forwarding instructions you mentioned. No limit on bandwidth - the best (and most common) option
2. Relay - for whatever reason your client cannot reach the server (CGNAT / port forwarding not possible / firewall on client side etc), Plex will act like a man in the middle & limit the connection to 2mbit. (Yup, megaBIT).

I switched away from Plex last year because they wouldn’t let me connect with my box in Hetzner. I’m now using Emby, ironically I’m also paying for Emby’s monthly subscription. Not because I believe I need to, but because I want the developer to continue to work on it.
