Setting up a remote work environment?

Question

SSH

The essence of the problem is to set up a home computer as a powerful remote development machine. The idea is to code on Macbook 12 (i.e. ultra weak hardware) - a super heavy web application in Python and Node.
As I already figured out:
1. You need to connect a static IP from the provider, configure the router to external ports in order to see the localhost of the machine, or, for example, use a service such as ngrok.
2. You need to somehow connect to the computer via ssh in order to be able to edit files. Or use a service like Syncthing.
3. You can also connect via ssh and run the server, or install some new packages, or run migrations in Django
4. Another bonus would be good sometimes to go through the virtual desktop. For such purposes, you can use for example VNC Viewer.
Question - is there an adequate instruction somewhere on how to do this? I flipped through the floor of Google and, apart from the abrupt manuals for 2007, I did not find anything sensible.
