Saint-Pierre and Miquelon

I'm hoping to take a trip to Newfoundland in June 2021 but I'm wondering if Saint-Pierre and Miquelon is worth travelling to?

How much is it round trip on the ferry from Newfoundland to the island per person? Can you take your car on the ferry?

Do you need to have a car in order to get around the island or are there things to do as soon as you get off the ferry?

From reading some of the other forums it sounds like there's a museum about the prohibition and one that contains a guillotine. If this is correct, would someone be able to tell me the names of these museums?

Roughly how much time would be suggested in spending at Saint-Pierre and Miquelon?

Any info would be appreciated!

Thank you!
