Synonym discussion
Sense: adverb/1
All four can introduce a key point, but they differ in strength and register. Significantly is the closest neutral synonym and works in most contexts. Notably places more focus on the fact being remarkable or worth singling out, often in lists. Crucially carries a sense of necessity — without the point that follows, the outcome would be different. Above all is the most informal of the group and suits everyday conversation or personal reflection: 'I want a job that pays well — above all, one that I enjoy.' In formal academic or business writing, more importantly or most importantly are the safest choices; significantly and notably are also common but slightly weaker in emphasis.

Etymology
Formed by adding the suffix -ly to the adjective important, which came into English from French (important) in the 16th century. The French word traces back to Latin importans, the present participle of importare — literally 'to bring in,' but also used figuratively to mean 'to be of consequence.' The discourse-marker sense (sentence adverb) developed in the 20th century and is now the most common use.
