It really 100% depends on the doctor. Some will trust you more for using insider jargon, some will trust you less because you "know the right things to say." Honestly if there's one thing I've learned about healthcare from the inside it's that two doctors can have completely different practices and each one will insist their own is just the usual evidence-based standard.
So no, there's no codewords. Sometimes I think you can get bonus points for respectability shit--show up dressed nicely, speak very calmly and objectively about your problems--but sometimes the doctor will see that and say "seems like you're functioning fine right now," so again, no universal advice.
The only real advantage nurses have is word of mouth--if a particular doctor is a known asshole to everyone, word tends to circulate around the local healthcare community. But if we don't know a doctor's reputation*, we're taking our chances too.
*or if he has a good reputation but unfortunately the bug up his ass is your specific condition. every doctor has at least one bug up their ass. they could be the most compassionate, empathetic, progressive doctor in the whole world but there will always be one condition or treatment where every mention of it sends them into ranting fits about how it's a MYTH that BIG PHARMA has just CONVINCED ALL THESE PEOPLE they have some CONDITION but maybe they just need to TAKE CARE OF THEMSELVES and
and I know you're thinking this would be, like, fibromyalgia or ADHD, but sometimes it just comes straight out of left field that this particular doctor refuses, on ideological grounds, to see anyone with "so-called psoriasis"
