I think they work great for a hifi system!
There is a ton of misinformation with the term nearfield and its use for the home market. Nearfield, midfield, farfield or main monitor are pro terms and basically have two criteria that needs to be met. One is that the sound is coherent at that distance. For instance a large tower speaker will not have coherent sound from its woofers, midranges and tweeter from a half meter away. This would not be considered a nearfield speaker. The other is SPL/ volume level. It ineeds to reach a certain volume at a given distance. The further away one listens, the larger speaker will be needed to reach that volume. In the home market not everyone listens that loud, so they might not need the larger speakers. If you want louder, you need a larger speaker like a tower in the home market or one of the larger monitors in the pro world.
If you sit further than 3m the sound is not going to all of a sudden turn to garbage and become distorted, crackling, scratchy or sound terrible. Sound disperses based off of physics. You will find consumer speakers that behave simiarly to these that people use for hifi. Their directivity is similar, their frequency response is similar. Their preference score is similar. Nothing about this means it can't be used further away except if a louder volume is desired then you need a larger speaker. The Kef R3 or R3 Meta come to mind for a similar design and people use them all the time for hifi listening more than 2-3m away. For some reason people think because this is labeled nearfield that you can't use it further away.
If these play loud enough for your needs than I think it is an excellent choice. I would go with the bigger sub as suggested if possible.
