Looking for resources where N2 grammar is profusely used

I’ve been studying on N2 textbooks for a while now, dedicating myself mostly to grammar and 読解. What I found is that the passages that are included in my 読解 textbooks don’t contain as much N2 grammar as I would like. I feel like I don’t get much exposure to some more formal and generally rarer forms, such as

• に伴って　（自由には、それに伴う責任がある)

• を問わず　（学歴、経験は問わず、やる気のある社員を募集します）

• まい　（彼は何も言うまいと思ってるらしい）

• \~さえ\~ば　（道が込みさえしなければ、駅までタクシーで10分ぐらいだ）

• \~も\~ば\~も　（父はお酒も飲めばタバコも吸うので、健康が心配だ）

• に沿って　（決まった方針に沿って、新しい計画を立てましょう）

• にもとより　（私が生まれた村は、電車はもとより、バスも通っていない）

• をめぐって　（その法案の賛否をめぐって、活発な議論が交わされた）

• ばかりか in place of ばかりでなく

These are just a few examples. Again, I’m not saying that my 読解 textbooks never ever contain any of these constructions, yet at the same time, I feel like I don’t see them enough, so I’m afraid I could potentially forget about them. Can you recommend to me some extra resources? I think newspapers are filled with these expressions, but whenever I read one I feel overwhelmed (so much ink!). What should I read? The 恐ろしい newspapers? Thank you \^\^
