Certainly, France has the better roster. Yes, on paper they should be favourites. However, odds of about 1.90 are a bit short for a World Cup final. I am going to dismiss the fact that Croatia has more play time as a factor. At this level and given the stakes these type of considerations are probably insignificant.
Both teams. I think, are going to be very careful and not risk much. This gives the the draw result, I believe, an increased likelihood. 
I think Croatia will win in extra time or in penalties. France has the better roster, but the momentum is with Croatia. In all three of the knockout matches, Croatia came from a goal down to qualify. This could be read as "when is their luck going to run out?", but I think it reflects focus, resolve and determination. 
The Bets:
Draw: 5 units
Draw / Draw (halftime / full time): 5 units
0-0 exact score: 1 unit
1-1 exact score: 1 Unit
Win Croatia in extra time:5 units
Win Croatia in penalties: 5 Units
Croatia to win outright: 10 units
Good luck to all in their bets.

Great perspectives and advice, here! In the 16 knockout out round I am going for a strategic bet:
Draw result for the following five matches:
France - Argentina
Uruguay - Portugal
Croatia - Denmark
Sweden - Switzerland
Colombia - England
The odds indicate a "balance" between the teams and, I think, that makes the draw a likely result. With odds between 2.90 to 3.30 the risk is worthwhile. The slight exceptions are the Croatia - Denmark and Colombia - England matches. Neither Croatia or England deserve, in my opinion, to be so strongly favoured against their respective opponents. 
Assuming odds of about 3.00 for each draw, one would need 2 draws to make profit. Actually, I would break even because I can't resist placing a 1 unit bet on the 5 match parlay. Overall, the draw bet is risky, but has value. 
I am going to go one step further and bet the 1-1 correct score for each match with odds between 6.00 to 7.00. Here, you need one winning bet to profit / break even (depending on whether you bet the 5 match 1-1 correct score parlay or not...). There are bookies that will return the bet in the event of a 0-0 draw.
Good luck to all in their World Cup 2018 bets....
