Choosing a server for 1s in my case?

Question

1C

Greetings!
Task: it is necessary to install 1c so that it (to the data from its database) has the ability to connect third-party scripts from the Internet.
Correct me if I wrote something wrong:
1. We get a static ip and fasten it to the server?
2. We put Windows on the server. Does it matter if windows server or regular windows 10?
3. Set up free access 1c to the Internet.
Questions about dedicated servers:
4. Does it make sense to take a dedicated server instead of a server in our office?
5. Does it make sense to take not a dedicated server, but for example vps?
Question about Linux:
6. If we take a dedicated server or vps, then how difficult will it be to install and configure 1c on Linux?
Thanks in advance for your extended comments!
