I'd say there's some
justification for the muh consistency argument, depending on clientele. For instance, if you're outfitting a police department full of high school dropouts with insecurity issues, it's in your best interest to keep the manual of arms as simple as possible, with as many passive safeties as possible, for ease training and to avoid fuck-ups. For conceal carry it's more personal preference; however, as you point out I think anyone who carries should be well enough versed in fundamentals that a different trigger pull doesn't destroy your accuracy. If you can only shoot well with one gun, you're not a good shooter. There are other considerations besides muh consistency, though. Striker-fire guns will always have a lower bore axis than an equivalent hammer-fire. You'll always need space below the bore axis for the hammer to travel through, because it needs to rotate down. It's debatable whether this difference is enough to matter, since you can still get a really low bore axis with hammers--just look at CZ and what they do by putting the slide rails on the inside. But you can apply those same tricks on a striker gun as well, so it will always be that much lower. Again, whether the difference is enough to matter is personal preference, as is whether it matters more than other factors. I personally prefer hammer-fire DA/SA guns because I like having the option of that crisp SA trigger should I need it, while having the safety of a long pull. And with modern guns, that long pull is smooth enough that it doesn't really bother me or adversely affect my accuracy.
Here's where strikers really annoy me, though: they're almost all the fucking same. They're almost all copies of the Glawk mechanism, where the striker is partially cocked by the slide going back, and partially cocked by the trigger. This is not the only way to do strikers. Strikers are just linear hammers, and if there was a little more variety in the market you could get all the benefits hammer fired guns have, but with the bore axis benefit of strikers. You can make DA/SA strikers with decockers, and you can make SAO strikers. There are even a couple examples of these on the market--the walther P99 is a DA/SA striker, and the Heckle My Koch VP9 is a single-action striker. But there aren't nearly as many examples thereof, so you're usually stuck with "I can't believe it's not GLAWK," and the false dichotomy of DA/SA hammer/partial-cock striker.
