Can you show us the entire room? Why would you choose to place it off center? Is there a reason? A focal point that we don’t see? More photos, more information, and a measured floor plan, if possible, would help.

The reason I’d go off centered is because otherwise the sectional arm will block the flow of traffic. There is an entrance to the room there

An asymmetrical art arrangement will make the off centered sectional irrelevant.

follow up question… would the other orientation work as an L sectional? Or is that incorrect bc it faces away from the entrance to another room?

Consider a sofa and comfy accent chair for more openess to entry points. Room looks narrow and a sectional limits arrangement options.

Draw and measure the darn room. Show dimensions every foot and inch for every wall and window and passage. Show the dining beyond in your drawing along with ITS dimensions, same way.. Add pictures and before you post? Orient them correctly.

If you have the entire floor plan for the house? Post it by taking a pic, file as a jpeg and upload that too

In the end you do what works functionally but as already suggested your options increase with smaller pieces to work with.

If i want a sectional, whats the best orientation?

It’s hard to give an opinion on the best orientation of a sectional without a floor plan and measurements. What is on the wall not shown opposite the couch?

Position a sectional between the two windows.

Make sure whatever you're using for a dining table is confined to the dining room area and not slopping over into the living room

I like the way you had the sectional layout in your first photo. Then you could add one chair in the bay window area angled towards the television. Your wood floors are very nice.
