From my year of Ch3+, Channel 3's online service. Around US$30/year. This page lists the lakorns available with English subtitles. The Secret of Us, too. Some are probably available elsewhere.
A Tale of Ylang Ylang - two halves with an abrupt change, ultimately about the dignity of women.
Rivalry - 1/3rd meh, 2/3rd much better, last 3rd continues to shift, reveal new layers and depth.
Switch of Fate - Complicated impossible story well-explored.
Rakkaew/The Root - Complicated, messy, intense psychological lakorn about trauma and abuse, sexism, power and calls for social change. (MDL's tags are completely wrong. I'm trying to get them fixed.)
You Touched My Heart - Calmer lakorn with quiet depths in what's framed as a side story.
On one31's official YT
Khun Chaai/To Sir with Love - For all that western viewers focus on the romance between men, this is really a story about women. Excellent writing and pacing.
Love in Twilight - Fast-paced fantasy lakorn.
Curse of Saree - Fairy tale lakorn where all of the far-fetched nonsense works because they get the emotions right.
More I haven't seen yet, and some I have and didn't get on with here.
