It's symmetric pawn structure (not much play, just try to make your pieces better) and you've been left with your "bad" bishop (pawns on the same color as your bishop). Mainly as black I'm worried about my bishop.
The only try for play is the pawn break on e5. So e.g. Qd6, a6, e5 as the next 3 moves if white doesn't prevent it. This will also release your bishop by moving the e6 pawn.
For these reasons 9...d5, while reasonable enough, was not a happy move to play. The bishop on c8 will have a difficult time moving outside of the pawn chain. Starting on move 9 Black would rather try something like a6, Ne7 b5 Bb7 if possible (and now the bishop is on the open long diagonal).
As for long term play there really is none in this pawn structure. After e4 by white or e5 by black that will change, and one player will probably get an isolated pawn. Then you'll have to standard try for active piece play in the middlegame (by the side with the isolated queen pawn) vs real winning chances in a heavy piece endgame or bad bishop vs good minor piece endgame (for the other side).
Hi, sometimes when I play, I fully develop my opening and am unsure about what to do next such as this:
Could someone advise me what to consider and do in these type of situation?
