I find Paddy's comments quite interesting. I alternate between the French and Caro, but I don't really think that the French is easier to play merely because it leads to a more predictable pawn structure.
For my repertoire, the C-K leads to about 6 pawn structures at most:
3. ed5 cd5 4. c4
3. ed5 cd5 4. Bd3
3. e5 Bf5
3. Nc3 dxe4 4. Nxe4 Bf5
3. f3
2. d3
the French leads to:
3. e5
3. Nd2 Nf6 4. e5 Nfd7 5. Bd3 c5 6. c3 Nc6 7. Ne2 cd4 8. cd4 f6 9. exf6
3. Nd2 Nf6 4. e5 Nfd7 5. Bd3 c5 6. c3 Nc6 7. Ne2 cd4 8. cd4 f6 9. Nf4
3. Nd2 (universal system with ...g5 moves or pawn grab on d4 also lead to unique pawn structures)
3. Nd2 c5 4. ed5 Qd5 or 4... ed5
3. Nd2 Nf6 4. e5 Nfd7 5. f4 (or 3. Nc3 Nf6 4. e5 Nfd7 5. Nce2 which may be similar)
Wing gambit 2. Nf3 d5 3. e5 c5 4. b4 leads to fairly original pawn structures
Two knights 2. Nf3 d5 3. Nc3 often leads to quite unique pawn structures too
3. Nc3 Nf6 4. Bg5 and now 4... Be7 5. e5 Nfd7 6. h4 is quite unique in its own way, while the (probably more interesting) options 4... dxe4 and 4... Bb4 are also very different fare.
If 3. Nc3 Bb4, and u either play a poisoned pawn position after 7. Qg4 or a standard Winawer position after 7. a4 or 7. Nf3 etc, White also can play numerous deviations on the 4th or 5th move which might lead to different pawn structures (e.g. 4. Nge2 or 5. Bd2)
3. ed5
2. d3, 2. b3 etc
Often there are also positions with ...Nh6, Bxh6 gxh6 too.
I think Black needs to master at least 6 different pawn structures in the French from the list above...As you can see I can't agree that Black needs to master any less pawn structures in the French than the Caro, but that's just my opinion !!
Well, Black does not need to play
3. Nd2 c5 4. ed5 Qd5 or 4... ed5, so we can cross that one off.
"Two knights 2. Nf3 d5 3. Nc3 often leads to quite unique pawn structures too." - only if Black wants it to - there is no theoretical problem with 3...Nf6.
I appreciate what you are saying, though, and perhaps we are just using the word "structure" slightly differently.
I would say that one of the main characteristics of the French is the persistence of the characteristic e6,d5 structure well into the middle game and often the endgame.
Of course, different variations produce slightly different structures (well categorized in Mastering the French by McDonald & Harley, in ten (!) chapters) but most are just different evolutions of the same basic blocked French centre. That's its attraction in fact - Black might be theoretically a bit worse (in fact I'm sure he is worse in most lines), but this is compensated by the fact that he is generally fighting on ground of his choosing, or at least on very familiar, or similar, terrain.
As Ziegler shows in his French Repertoire DVD, it is possible to devise a French repertoire that reaches the typical blocked French structure probably more than 90% of the time.
I was struck by these words of GM Daniel King writing in the Guardian:
"As with all openings, however, there are areas of difficulty. How to time the thematic ...f6 break? How to get the so-called "bad French bishop" on c8 into the game? How to prevent White establishing a knight on d4 - especially unpleasant if Black's own knights and dark-squared bishop have been swapped off?
Preparing a new opening involves memorising the most common variations (sorry, there's just no way round this), appreciating the main strategies, and studying the most important games. A tall order. But with the French, the same pawn structure often recurs: White pawns on d4 and e5, and Black's solid pawn chain d5, e6, and f7. Even if a variation looks unfamiliar, an understanding of the structure should help you devise a strategy. At first Black's position appears cramped, but the central pawn chain gives enough security to counterattack on the flanks."
