My own reasoning for playing 3 Nd2 with White is that I don't feel especially comfortable with any line against the Winawer. Besides, sub 2400 level, in my experience, you get 3...Nf6 most of the time anyways - 3...c5 are fairly "un-French" positions. I'm also not convinced White's cause for an advantage is hopeless; after 4...ed5, there's a lot of positions where (in principle), White is playing for two results, while after 4...Qxd5, judging from what I've seen of the Ntirlis/Aaagard repertoire, Black has to be very precise to equalize. I don't think 4 Ngf3!? cd4 5 Nxd4 is so simple either.
I used to play 3. Cd2 until I stopped playing 1. e4 ever again, like you say even worse I found was to have to face the Winawer (and the Classical was no fun either to be honest).
After 3...c5 if White wants to muck up the position earlier with 4. Cgf3 cxd4 5. Cxd4, I remember that here on ChessPublishing they had some coverage of 5...Cf6 6. exd5 Dxd5 7. Cb5 Dd8. I would not want to try for an advantage here for White.
4...exd5 is good if Black is a good technician/endgame player. If they have problems handling the IQP and White is the good technigian, then it gets complicated of course.
3...Cf6 is good but more static. I would avoid the ...Cxf6 lines and go for ...Dxf6 like in Berg. I notice that in under 2300 people like to play ....Cxf6 lines, mishandle the moves after theory and then get a strategically lost position.
