Do the stairs go up or down? If there is no second story, consider a Sun Tunnel skylight for the hallway.

I have stayed in a cottage with a french door to the bedroom, and I slept in our sun room with a french door when I had Covid. In both cases, the lack of privacy (even with curtains or blinds over the windows) made it not the most pleasant experience. I would never want french doors to a bedroom, even if it was a guest room. I would also want more privacy in an office, if I ever used it to work from home.

Thank you @AnnKH. The stairs go down. We don't have an option to add skylight for the hallway because of our current roof structure.

By privacy, do you mean noise from other rooms? I thought we could add a blackout curtain or mini blinds to the glass door for privacy.

Could add a transom over the door?

What about a double door? Most of the time it would be open, right?
