Yep, agreed - the whole area of how different people perceive taste and simply what you do/don't like is a minefield.And so we come back to the vexed question of taste. These unfermentable carbohydrates include dextrins and trioses, which, as you say, add body and mouthfeel to the beer, but they begin to be broken down by salivary amylase into monosaccharides like glucose, which to me is sweet and even cloyingly so. Of course, if you down a pint of beer in one, the enzymes in the mouth don't get chance to work on it.
On the whole, I don't like sweet-tasting things, but that's a matter of personal preference.
I've made a couple of beers that were verging on being cloyingly sweet but I put that down to the malt rather than the mash temp. One was with caramalt so won't rush to use that again, the other used pilsner malt which I've read can impart a honey-like sweetness - I dealt with that using a dry hop. On the other hand I've never perceived an issue when I've used carared or dark crystal malts.
At the end of the day I think just brew what you enjoy drinking
