I copied a tutorial here: Thanks to the built-in Wi-Fi, the newest version of the Raspberry Pi is more useful than ever for networking projects. We recently showed you how to use your Raspberry Pi as a wireless access point – a router, essentially – and now we have a project for you that builds on that. You can use your Raspberry Pi as a VPN access point, ...

The question is very good explained with the diagram. But, sorry, it also shows that it is a very complex situation I can't give a detailed answer without access to the network to analyze its behavior step by step.

You asked five questions. This is usually not the optimal format for this site. But I see your problem and will give some information how I would solve it. I prefer to Use systemd-networkd for general networking because it can do many things out of the box. I need some advice on selecting an OS. I have downloaded Raspbian (32 bit), Ubuntu 20.10 (64 bit) and ...

As you noted you will use a route to the internal pc using the RasPi as router. So you must have a different subnet for the internal pc and using the RasPi as gateway to that subnet. For this the RasPi needs at least two interfaces, one connected to the virtual private network 10.199.0.0/16 and one connected to the subnet of the internal pc. For my example I ...
