I would say I agree. That being said, my experience is biased from working in Big Tech where the accents are on such a wide spectrum that people have no choice but to develop a "flexible" ear.
I've worked in universities and in tech, in New Jersey, LA, and Silicon Valley, and I feel like I can understand just about anyone's English.
Ironically, the ones I have the hardest time understanding are almost always Brits.
My spouse finds it amusing, which is probably the biggest benefit, TBH.
