I want to ask are there beneficiaries to this war and in what ways are they benefiting from it.
It depends on the scale of the war, the region and how many or who is involved in the direct armed conflict. The chaos large scale wars like the two European Wars also known as World Wars 1 and 2 create benefit those who stay far away from that chaos like United States. In WW2 for example, US benefited the most since it was far away and wasn't impacted as much as say Europe itself which then led to giving US tremendous amount of power which they abused in the past 80 years.
The Russian-NATO war is a medium scale war at best since it is focused in one small area of the world and the impacts are different depending on the distance and involved in the actual conflict for each country.
For example US like the WW2 is benefiting the most since they could successfully rescue their failing economy for the time being by creating more market for their exports (eg. LNG to Europe or the massive increase in weapons sale) that couldn't have existed without this war.
Other countries like Europe (different countries in the region with different degrees but all the same) are negatively impacted since they are being abused by US (ie. selling much more expensive LNG to Europe instead of the super cheap Russian gas they used to receive) so the impact is huge and negative. Like the ongoing deindustrialization in Europe.
Other countries that are also far from this conflict are seeing a range of different effects depending on their involvement and level of independence. For example a country that lacks independence like Japan is being forced into suffering negative economical impacts while countries with more independence like China are taking advantage of this situation and are expanding their economy (China is actually reporting high growths these days!) by having access to cheaper energy, taking over markets that were left by Europeans, attracting investment and industries that left regions like Europe, etc.
With the rest of the countries being in between like Turkey, India, etc. that are experiencing both negative and positive impacts. Like Turkey taking advantage of the chaos to seek benefits geopolitically speaking.
That's just a summary though, your question can't be answered any better due to the broad nature of it. It is best to analyze the situation per country not as a whole. For example even in a region like Europe there are major differences between each country like Italy seeing a different impact than France for instance and they are both different from a country like Latvia in Eastern Europe.
