Your points are all very relevant for the classic software distribution model. But many software companies are avoiding the distributor model. For a SaaS startup or an App, their first market is generally all English-speakers across the world. They keep the software simple, their costs low and they don’t need distributors.

Until their software mature and they have complex enterprise versions, sales teams, product marketing, rich localization.

As a Brit, I can confirm we’re not really European It is a natural 2nd market as the localization is much easier in the same language

When companies go in the other direction the dynamics change. For a UK company it is very difficult to establish a strong position. Our home market is full of US vendors!

Non-English speaking countries have the advantage that they can grow their position at home. Treat that marketing as their testing ground and when they know they have a well established product-marketing fit then they can invest in expanding to the English-speaking world.
