Do nothing until all of your furniture, rugs and window coverings are in place.

I agree and BTW I often ignore corner fireplace when placing furniture they are IMO the worst possible item in a space.

Since these corner FP rooms come up so often, I just keep these floor plans in my file. See if one of these might help you decide what you're doing. Likely you will end up with art or wall decor over the FP.
