IPTV noob requesting assistance

Hello All

Long time lurker here and on IPTV Reviews. I currently have the standard cable/internet setup but I'm tired of paying for cable, useless channels, no content, good channels behind paywalls (like HD channels etc) and I barely watch TV nowadays since I have little time

I have browsed this sub for a while, read reviews online, checked some other sites, etc. But the more I search, the more I browse, the more I read, the more confused I am. I was hoping someone here can clarify some things for me if it's not too much trouble

1. Using a VPN is a must, no problem there. However can I use the VPN just on the device that I will be using for IPTV? Due to work restrictions I cannot use a VPN for all my connections as I work at home and need my own countrys IP address
2. Coming from the previous question. If possible I would like to avoid having to use my PC to stream. I would like a device 4k capable and a bit cheap (the idea is to save money from the cable service after all) so I was thinking about the Roku or the Fire stick. What are the differences between using USB and HDMI connections? Is there one that has HDMI and wired ethernet connection?
3. Are there devices that have a regular web browser? I have some local channels I like to watch and they are definitely not going to be on a provider (I live in a small country)
4. With the small country in mind, is it possible to use services like Netflix, Amazon Prime and Hulu with a VPN as if you were in the US? Is it recommended? Or perhaps just an IPTV provider is more than enough?
5. On the provider side, are there ones that only provide a "small" set of channels and mostly movies? I really don't think I would watch the local news channel from Netherlands. Can I pay for only the channels I want?

I would like an experience as close to "regular TV watching" as possible. Thanks for reading and responding
