My house was built in 1891 and published in The Scientific American Architect Supplement the following year. The first floor ceiling height is 10-0 and the door heights are 7-0 . The second floor ceiling height is 9 ft and the door heights are 6-8. There are several 6-0 wide double-pocket-doors on the first floor that are 7-6 tall. I would support to the OP's philosophy about tall doors but I believe that proportion is also important so when a doorway gets taller it should also get wider. Therefore for normal 32" doors I would stick with the lower heights and avoid transoms unless they are needed for ventilation.

E K, after extensive deliberation, we have decided to keep standard height interior doors throughout (6'8"). We are going with higher windows and sliding French doors in rooms with higher ceilings. I ended up deciding that the 6'8" interior doors looked fine and that windows can be set higher than the doors (I looked at lots of pictures and actual houses). I actually drew several walls to scale with the 6'8" doors and higher windows to ensure I would like that look. I decided the 7' doors were an unnecessary expenses and wouldn't look that much different from 6'8" doors. I think the higher windows will bring in more light and help the ceilings to look taller. There is one bedroom where I have one 8' wall that slopes up to 9' and I will have windows on both these walls - that was my trickiest problem. In that room, I've decided to have 6'8" window height on the 8' wall and 7'8" window height on the 9' wall with 6'8" windows. Its not built yet but I hope it looks ok. Below is a house that helped me think through my decision. It has higher windows than doors. In addition, in one room the windows on two walls are set at different heights. I think it looks ok and I think the sloped ceiling in my room will make the varying window heights look even more intentional.

In fact, I will be doing 8' sliding doors and windows set at 8' in our master bedroom that has 9' ceilings. This room will also have 6'8" interior doors. I can post pictures but it won't be built for several months.

It might help if you post some pics of your exterior and what your vision for the interior is. If you look at Mediterranean styled exteriors, living rooms, etc. on this site, there is a ton of leeway on trimwork. What you've chosen could very well fit your envisioned style or it might not. I would think leaning more transitional than modern would be a better fit, though. For instance, I love this Mediterranean style: https://www.houzz.com/hznb/projects/il-nostro-sogno-pj-vj~2678422 I think your chosen trim profiles *could* work with something similar ^^^.

I was the architect on a project that someone else designed, I oversaw the design and production of the construction documents. The designer caled for an seven foot high doorway to the kitchen, next to a window with an eight foot high header height, next to a door with an seven foot high header height, next to a window with an eight foot high header height, next to a door-wall with an eight foot high header height, next to a window with an eight foot high header height, next to a window with an ten foot high header height. There were many factors involved that in theory would make it work, and in reality it did work very well.
