The standards you've described are totally reasonable! This sounds like an amazing opportunity for you to have a really wide impact and a great chance for the company to level up their game using your experience. I'm sure you've thought about this already but it doesn't have to be a "fight" - in many cases what people need is some appealing reasons, e.g. describing how their world would be much more amazing if they implemented X, Y and Z. Depending on the size and stage of your company it might actually make sense to do it in a 'quick & dirty' way (e.g. dominating the market might be more important at an early stage than doing it in a sustainable way) but even then they (tech decision makers) should be aware of the tradeoffs and if they are, they should be communicating the reasons to the whole company.
