I bring up these failings in the west to show that they are not an inherent part of socialism, and using them to dismiss socialism is not correct.

It's not about absence or presence of these failings, it's about the degree of them, and socialism (USSR style) has very serious levels of these failings. Western societies have failings too, but on balance, and on average, they represent a better outcome for the citizens.

| The siege socialism mentality taken on by the Soviet Union did have many negatives for those living in it, including lack of choice in products and lack of freedom of travel.

It's not just about lack of products or the ability to have a holiday in France, it's about the freedom to disagree, the freedom to express your ideas, beliefs and ideals in whatever language you want, or through whatever culture you want, and to expect fairness from those around you. The USSR failed in this and killed, imprisoned or tortured those who did not comply with often toxic cultural norms. It was traumatic for those who had to live through it.

| However as a system it raised the living standards of its people of what once was the backwater of Europe to an actual modern standard in a large part of the country. It did this in spite of its conditions following the revolution, which were much worse than those of the USA, and despite a destructive war fought in its borders which cost millions of its citizens lives.

Russia may have been a backwater of Europe, but other countries it conquered were flourishing and prospering nations (WWII damage notwithstanding). Just look at what those states have achieved since being freed from the USSR. The USSR wasn't some rising tide, it was a huge deadweight on the peoples conquered by the russians. The rush to join NATO demonstrates this. They weren't forced or tricked into joining NATO, they WANTED to join NATO. Think about why that might be? It's because they saw the USSR as such a horrific, traumatic period that they never wanted to be forced to participate in anything like it again. Ever. Period.

| The fact is socialism did work for the USSR, whether or not free market capitalism would have worked for it given its starting conditions is debatable, but I doubt it.

It may have lifted the standards of living for peasant russians further than they might. have otherwise expected, but vassal states were actually held back by the USSR. I'm old enough to remember the USSR, which I suspect you are not. I've spoken with family who were forced to live in the USSR. They disagree with your perspective. Vehemently.
