I feel bad that nobody is really giving you a straightforward, genuine answer so I'll try to do that. I'm gonna try to sum up the Hexbear viewpoint, stripped of any irony:

• Russia as a state is a chimera of the worst facets of the USSR and American-style capitalism, it is bad
• Ukraine has very similar issues, I would argue the problematic nationalism is stronger than you put it
• Russia was antagonized by years of violence in the Donbas region and NATO expansion
• The previous point doesn't negate the fact that Russia has committed the crime of starting a war of aggression
• Western support for Ukraine is not motivated by any noble ideals like 'defending democracy', but rather because the conflict harms Russia and provides a meal-ticket program for the military industrial complex
• As with pretty much all wars, the people who will be harmed the most are the working classes of all countries involved. Any serious person who calls themselves a leftist should recognize that the best outcome is whatever benefits those people the most.

As for your question on what the ideal outcome is, I don't really know what to tell you. I would like to see an agreement reached that minimizes the future risk of conflict, and for said agreement to be reached sooner rather than later. What that agreement entails would definitely need to be worked out through mediated talks. Do I think that is likely? No. What I think is very clear is that as things are the war is probably going to drag on for a very long time, kill a shitload of people, and end in a way that doesn't restore any stability to the region. The reason people here spend a lot of time shitting on all the people cheerleading the conflict is because they seem oblivious to that reality.
