My living room has a wall with a 10-foot-wide alcove, which has a set of windows that share a Craftsman-kinda window trim with a 2×3 capitol – maybe not the correct term, but see picture.
I have a 10-foot-long 2×6 board to attach above this, as a shelf. (I think it goes better with the trim style than a 1×6 board). But that’s heavy obviously so what method is good to attach it to the wall? Brackets? Pocket screws?
The wall surface is probably 1 or 2 layers of drywall or that grainy, concrete-looking wall stuff that’s in the kitchen.

So, the good news is that you almost certainly have solid wood all above the window to fasten to. This makes it a good candidate for blind shelf supports. (Google, but rockler sells them...)
Alternately (and cheaper), you could have inverted L brackets. Paint the top legs wall color and you'll stop noticing them. Only your fussiest visitors would notice. It's up to you to decide how sturdy you need, but if you find that you haven't got enough to be comfortable, simply add a few more.
