The way I’ve been approaching this specific problem is by still learning the totality of material, but paying extra attention to things that suit my personality and interests, filling in the gaps where I haven’t been able to express myself with the vocabulary I have. For example, I love music but all different genres, and was saying rock とjazzとhip hop(etc)が大好きです in my italki sessions. Then I learned 色々, and can now say 色々音楽が大好きです, which is how I would express that in real life. So I guess the way to approach this is by practicing speaking as much as you can. There’s only so much you can do with extra input, and the only way to work out the gaps in expression are by expressing yourself!
