In think 95RON (E5) will be around for a good while, so don't worry about it too much. Your car may last long enough to see the day when E10 is the only fuel you can buy. Read this from the RAC What is E10 fuel and how will it affect you? | RAC Drive
Peugeot indicate all petrol vehicles made after 2000 are compatible. I suspect most of the fuel system on Ph2 306's would be able to handle it. The lines that run to the fuel tank in a 306 are nylon and would probably be ok. I would have thought the fuel rail & tank (plastic) would be fine too. Same for nitrile o-rings used for the injectors as they're pretty standard across more recent vehicles too. It's easy to upgrade any fuel lines that aren't nylon. (There are some bits near the fuel rail but they're very short runs).
My main concern would be with some of the rubber components in the in-tank sender unit. (There's a non-return valve in there). Tbh, if that's the only thing that gets trashed I'd call it a win, but this is all academic ....as I say, it looks like E5 will still be available, if not more expensive.
