Hit a brick wall learning French (B2/C1)

Tl;dr - Resource suggestions for B2/C1 level French

Hi there, I’m looking for some advice as I just feel like I’ve hit a bit of a brick wall while learning French. In all I have probably been learning for 15 years, first at school, but then it really took off when I was around 17/18 and I got from A2 to B2 very quickly through speaking with a French bf 😅. I travelled in a French speaking country for 4 months a few years ago and quickly gained C1 level speaking and listening. My reading and writing and grammar stayed a mediocre B2. Now I’ve had other things going on and although I want to keep up with my French I can’t seem to find any way of learning that brings me much joy and motivation. I know at this stage reading books, watching Netflix is important but I can’t seem to find one series to stick to, or a staged program of resources that will allow me to see progression over time. I don’t have much time to put into it, maybe 30mins to 1 hour of desk studying a week. Eventually I want to use my French in a medical setting.
Thank you for entertaining my slight moan, any advice would be very welcome!
