Chimney & Gable End Recommendations?

Hi! Don’t mind my non fancy house. We bought in 2020 before the market went wild. Since then, we’ve had another baby and outgrew it. Instead of selling and buying something way overpriced with a higher interest rate, we converted our 2 car garage into living space. One thing led to another and now we’re residing.

We also added a covered roof over our front door. Eventually we need to reface our chimney and I’m lost on what to do. Also struggling with choosing how to finish our gable end! My siding is a dark navy blue. I really love the orange wood tones with this color. (See inspo pics 2&3). We did buy some cedar boards to wrap the posts with but how should the gable end be finished? I’ve asked before and lots of people said to use the siding up there. With the way it was built, I’m not sure if we can do a fancy gable end? I could eventually add something like the last photo?
As far as chimney, what would flow with this look? The chimney is such a large focal point. I’m struggling and we’re trying to get the outside of this house done before snow flies!!! We’re doing all of this by ourselves and it’s stressing me out lol thank you so much.
