I'm learning danish while living in Denmark. I have terrible ADHD. I think the biggest two things I've found that's helped my pronunciation and helped a lot with understanding casual spoken speech has been a) singing together with others. I think the dopamine and activeness of trying to predict how a line will be said Vs how people actually sing it shows how words can be changed and chopped up and how they can't (how do people naturally change or squash together syllables to fit the song and/or rhyming)
B) is podcasts. I have found them very good for commuting/gaming. At first they were language learning ones specifically but now its stories, trivia, etc. I still really struggle to listen to podcasts with multiple hosts but im getting there. I think seeing stuff with subtitles is a bit of a trap - i found myself quite reliant on them and couldn't understand anything with them off. Much better to struggle through podcasts bit by bit, pausing where I need, and after a couple of them I was mostly up to speed
