Furious represents extreme anger, while angry is a more moderate emotion, showing a clear intensity difference. Annoyed and irritated are very similar in intensity, as are concerned and worried, and pleased and delighted (though delighted is somewhat stronger, the difference is less dramatic than furious versus angry).

Thorough means complete and exhaustive, which aligns with 'examining every detail with meticulous care' and contrasts with 'superficial.' Cursory means hasty and superficial, hasty means done with excessive speed, and preliminary means introductory or preparatory—all opposite to the detailed investigation described.

Request (formal) versus ask (informal) shows the greatest formality difference. While residence/home, purchase/buy, and commence/begin also show formality differences, the gap between request and ask is more pronounced in everyday usage and register.

Stalemate means a situation where no progress is possible, which contrasts with 'resolution' and matches 'both parties more entrenched in their positions.' Compromise, agreement, and consensus all represent successful outcomes that would constitute resolution rather than its opposite.

Contradicted means to assert the opposite, fabricated means to invent falsely, and eliminated means to completely remove.

Mitigate means to make less severe or serious, which contrasts with 'inflame them further.' Escalate, perpetuate, and intensify all mean to increase or make worse, which would be the opposite of the intended meaning suggested by 'rather than inflame them further.'

Autocratic specifically means exercising absolute power and making decisions unilaterally without input from others. Decisive means able to make decisions quickly, independent means self-reliant, and confident means self-assured—none specifically captures the lack of consultation that autocratic implies.
