I have been using duckdns for a few years without issues. It should be simple enough , just set up a cron job with your details as listed on their site where you configure it. This keeps your dns entry up to date.

This is when you stop owning a phone or just leave it in a drawer powered off until you need a 2fa key or something.
If you want a quick and easy way to share the odd file you could set up a syncthing shared folder and COPY things in to it that you want to share. When the other side MOVES them out of the shared folder they will be removed from the shared folder on your side.
The advantage of this is security. No access is given to your system. If your friends box is compromised you dont have an nfs mount or ssh key on their machine. The worst that can be done to you is copies in the shared folder are removed or malicious files are placed in the shared folder but they wont be able to execute.
You also dont need to open any ports for syncthing , it will use relays if it cant make a direct connection.

Lowest barrier to entry

I'll wait for the movie to come out
Dont install random shit and if possible have a phone just for 2fa
Just because the share price is taking a hit. It is about money and nothing else.

The ip shouldnt change unless the server is down for a period of time and the ip is dynamic.
If it is returning OK then it sounds like duckdns is working as intended
