I'm not sure whether, since this thread, there have been many others created with links to Thai (audio) youtube channels with Thai subs. I will copy this post in to one other particular thread I am aware of that lists Thai shows with Thai subs. Anyway, here are three series / channels that I like. I'll put the link to the channels and / or example videos

Two and three are of a similar ilk - travel / backpacking series, which I really love. Of course, dialogues featuring non-Thai speakers aren't in Thai, but you still have the Thai subs, throughout. Having bits of English interspersed with the Thai might irritate some, but predominantly they're in Thai.
All in all, plenty to binge watch if these are your cup of tea!
