You might actually try adding some sugar to the watery stuff you got by accident. Adding sweetness is easy, and can adjust sour products to your liking (I've done this successfully with very sour beers). I personally like the idea of tweaking the taste of commercial products.
Good insight on the two bowls for vinegar and oil.
I feel like a better way to approach this would be to stand on the shoulders of others and search around for product recommendations. Ie. this from America's Test Kitchen.

I apologize if this ruins any subtlety you were going for, but I'm thinking mostly about how these learnings can be applied more generally.
You kinda did what I think most people would do. The product is in bottles. There's no obvious way to tell how good the product is. So you use price point as a heuristic, and call it a day. But it turned out that with a little bit of thought, there was a reasonable way of judging the quality of the product.
So maybe the lesson is to give things a little bit of thought before assuming that they're actually difficult? This can be tricky though. "Operating on automatic" has it's benefits. If we always "took the wheel" in situations like these it'd be excessive, I suppose.
But I think the balsamic vinegar was a good example of a situation that might on first approximation seem "excessive"[1] to "take the wheel" on, but it turned out to be worth it. And I get the sense that there are a lot of similar situations where most people could benefit by "taking the wheel".
I remember early in our relationship, one of the first times that I went grocery shopping with my girlfriend we had an argument about this. I was "taking the wheel" and approaching everything pretty strategically. She didn't want to think so hard.
your points about taking the time to think through problems and how you can do this across many contexts is definitely what i was going for subtextually. so, thanks for ruining all of my delicate subtlety, adam :p
standing on others' shoulders is definitely a reasonable play as well, although this is not something that works great for me as a Canadian - international shipping is expensive and domestic supply of any recommended product isn't guaranteed.
Since you've not mentioned a specific brand, to make it potentially even easier for people to grab something they might like I suppose I'll go ahead and link to the following (which appeared many moons ago in a product-recommendation post on SSC), though note it's a bit less sugary than the one above, i.e. just 7g/Tbsp: https://www.amazon.com/gp/product/B00CMGRNAK
For a long time I only went to one specialty gourmet store for balsamic vinegar. Their house brand was thick and sweet and amazing on everything, from bread to salad to chicken. The gourmet store only stocked their house brand, and it had an entire dedicated shelf. As far as I knew, the house brand was not available anywhere else in town.
The gourmet store was slightly out of the way, and eventually there were times when I wished I could grab balsamic vinegar at the normal grocery stores that I did most of my grocery shopping in.
The first time I attempted it, I was rushed for time and it was a disaster. I knew the approximate price range that I should be looking at (around $25 CAD for a ~200ml bottle), but there were a dozen vinegars that fit the bill, and they all had pretty fancy looking packaging, and I was AP’d AF. I basically picked randomly based on vibes, and I picked wrong. The vinegar was the consistency of water, sour, and not fragrant at all.
The second time, I was ready. Recall that the balsamic vinegar I wanted was thick and sweet. It turns out that you can use your literacy skills and senses to ensure that the vinegar you buy are both of those things!
Again, first I culled all the vinegars that seemed to be priced way too cheaply – like under $10 for a sizeable bottle. Then I started systemically picking up the remaining bottles, and tipping them sideways. Most of the bottles were tinted but not opaque, so you can see the vinegar inside. Anything that moved like water I put back – those were a sizeable portion. A few bottles were truly opaque, those also went back on the shelf.
For the vinegars that flowed a bit more slowly, I turned the bottle around to look at the nutrition facts. Sweet vinegars are going to have sugar in them – no one has been brave and visionary enough to make fancy vinegars with aspartame yet. Thickness and sweetness turned out to be traits that were 100% correlated, at least in one direction: all the thick vinegars had sugar content of around 8-12g per tablespoon. I picked the cheapest bottle that met the two criteria to try. It was $2 more than the bottle I get at the gourmet store for the same volume, and slightly better tasting IMO. (I just checked the house brand vinegar I still had half a bottle of, and it has 11g of sugar per tablespoon.)

Bonus:
In fancy restaurants they sometimes give you bread and a bowl of nice vinegar and olive oil to dip it in. This is delicious, but we can do better. When the vinegar and oil are in the same bowl, the bread must travel through the layer of oil (hydrophobic) to get to the vinegar (water-based), and then back out through the oil. This results in bread pieces that have very little vinegar and too much oil on them. If you instead put the vinegar and oil in separate bowls, you can dip the bread lightly into the vinegar first and then dunk it in the oil. This results in a much better ratio of vinegar and oil on your bread.
Having fresh baguette slices and bowls of nice olive oil and vinegar out at a party has never been a bad choice in my experience. It’s not actually that expensive, and it’s vegan by default :)
