historical. No supernatural elements if possible
No supernatural complicates this. Thais can put a ghost in anything <3
The Death of Khun Phra (there's a ghost but mostly it's a murder mystery; historical setting, mixes old and contemporary references) Thai PBS, free to stream, look on MDL page for direct link or search on their vipa.me streaming service for the title.
Do you count time travel as supernatural? I peeked at your Dropped list to get an idea of what you didn't get on with. For reference, I'm not a fan of Hidden Moon either. It felt like a badly convoluted knock-off of I Feel You Linger in the Air, which itself was more a woman's romantic fantasy set with young men in a historical period.
These two are also time travels, but feel very different to me.
From Chao Phraya to Irawadee (Thai PBS) Grounded in the reality of their 200 years ago world, but there's a lot of back and forth which might be disconcerting. Very much a love letter to the dance and arts of that period. For a taste, here's the OST.
Royal Doctor (try bilibili) Fun, and mostly light. Time travel but no back and forth.
I felt like I learned a fair bit of history from both of these.
A Tale of Ylang Ylang - post WW2, no supernatural. The 1st half is very different in feel from the 2nd. (try bilibili. i watched via Ch3+, 1 month sub is US$3; 3 month less than US$5 until end of June)
To Sir, With Love (Khun Chaai) - (one31's YT), 1940s - there's some magic in it (use of herbs) but mostly it's family politics lakorn with excellent pacing and an emphasis on women's struggle to have agency and power in a period which limits it to their relationships with men. In keeping with that theme, western audiences tend to focus on the M-M romance rather than the women.
