Where's the instructions for being a good husband?
To be fair, the org does write articles about that too, so it's not just all on the sisters.
The problem is, as the OP says, that they obsess over things like whether he or she is pioneering or helps out a lot at the Kingdom Hall and on construction, rather than more relevant things to a successful relationship, like the kind of personal qualities and abilities that Beth Sarim mentioned.
Take that list of questions mentioned in the article, for example. The two placed at the top of the list are too vague and broad to give helpful guidance. What does "mature Christian" or "spiritual interests" mean? We know that in WT-speak these are code phrases for doing what is expected of them by the organisation, not really necessarily being a mature or spiritual man.
Most of the remaining questions are useful in assessing a potential husband, but again the last one - "Does he handle responsibility well?" - is automatically framed in the context of congregation assignments. Hardly the most important element of being a responsible potential husband. What about family responsibilities - to his ageing parents, for example? Or perhaps having a responsible role in his secular work, managing a team or doing a demanding job? Nope, not a word of those.
It's funny how any given body of elders - when caught in informal conversation - will bemoan the number of relationship problems in their congregation, yet these brothers never seem to put two and two together and see the link between that and the unrealistic suggestions put forward in articles like this.
