WK’s vocab is chosen to reinforce the kanji you learn and doesn’t necessarily prioritise the most commonly used terms. It also doesn’t highlight when you learn the kanji form of things commonly written in kana alone. Perhaps consider using anki / torii / kitsun to drill the 10k most common words if you want to focus on what you’re most likely to encounter.
The youtube channel of CureDolly also helped me a lot with important grammar basics. It got me on track to start reading native content, along with BunPro.
Otherwise, as @athomasm said, the forum has a lot of resources, both free and paid, so glance around, I’d say. 
Best of luck!
