What to do when both sides have everything defended?

Without going in too much detail about that particular game I think it's clear you could benefit from taking a quick look at general opening principles. The general ideas are to fight for the centre, (preferably quickly) develop your pieces and make sure your king is safe, to those ends I'd suggest some rules of thumb.

• Don't move too many pawns in the opening, try to stick with 2, maybe 3
• Don't move the pawns at the flanks too far, fianchettos can be ok, but moves like g4 makes it harder to keep your king safe further down the line
• Try to move each piece only once in the opening, with the exception of moves that win a tempo and some other advantage
• Get castled, we say the opening is (typically) over once the rooks are connected.

On that note I'd reccommend this video: https://www.youtube.com/watch?v=kURU67G98O8

All that being said: A simple idea if you're stumped on what to do is to identify your worst piece(s) and try to think of ways to make them stronger. In the final position you showed, for instance, your bishops and rooks are kind of doing nothing because the position is so closed. Bishops like long open diagonals and rooks like open files, so I might've tried something moving my king a bit more to the side for safety's sake, getting my rooks to the centre and then opening up the e- and d-files. Black will be in trouble if you get that far and he still hasn't gotten his king somewhere safer.

If you don't think you've got any shot at breaking their defense you can always offer a draw. Otherwise you're going to have to find a way to break apart the position, or wait for your opponent to do so. If the both of you wait then I assume your opponent will eventually accept/offer a draw.
