I work at Home Depot (Millwork Specialist) in the Door and Window Dept. We have a nice selection of custom interior doors from JeldWen and Feather River that would meet your needs including the Shaker style. They aren't cheap but they are good quality. Most of the older homes around here have the solid pine or oak standard 6 panel doors in them. The biggest concern is the size. A standard door is 28, 30, 32 or 36" wide by 80" tall. Some older homes have a 76" height which makes it a custom door now which means more $$$$. Measure before you go looking. We also carry the glass door knobs like you had in your post above. We have the whole knob system or just the replacement glass piece. Just tossing it out there to you before you have some Amish guy make custom doors for you -LOL! I don't get paid comission.
P.S. I wear a hat every day with my orange apron. The name on my apron is Terry "The Hat" LOL, people have no problem remembering me when they come back to order.
