A Eurail pass surely will be good value for your trip, you’ll travel some large distances and in many different countries.
Which pass you take, depends a bit on the travel days (the days where you get from A to . Best is to make a calculation from which places you visit.
Note that it’s not interesting to use a travel day for very short local trips (like Paris Versailles or Paris Disneyland), since local tickets for bus, tram, metro or local, suburban trains are very cheap. Eurail only includes mainline trains, no city busses, trams, metro’s...
Passes are really good value for longer stretches of travel, like Paris-Lourdes, Zuerich-Vienna,… Any train actually where you stay on longer than one hour.
