Stiff Soled Low Top Approach Shoes?

Just returned from a Dolomites trip (amazing) and was reminded that I have a gap in my shoe quiver. Basically, I noted the lack of support and rock plate protection in my approach shoes (TX4s) tromping around the Mtns. All of my approach shoes are “lowland” style or nice and soft and sticky but lack a rock plate needed for the higher peaks. I love (love!) my TX4s and also have a pair of Salewa Firetail 3s that work very well (slightly different shoes but both excellent). I’ve actually tried the Salewa Mtn Trainers and they’re exactly what I want BUT the last is slightly different near the toes and won’t work The Mtn trainer curves in ever so slightly near the small toes and has a pressure point.  I basically want a TX4 fit (nice, roomy toe box) but in a Salewa Mtn Trainer build.
Options?  Here are a few I’ve dug up.

Salewa MTN Trainer Low (this is the design style I want)

Garmont Dragontail MTN (these seem perfect but conflicting reports on fit)
SCARPA Zodiac Low (not stiff? not avail in US?)
SCARPA Zen Pro (too soft?)
Lowa Laurin Lo
Hanwag Makra Low
Aku Tengu Low
Mammut Ayako Low
Asolo Salyan
Asolo Apex
Milet Friction
Montura Yaru GTX 

Five Ten Camp 4s.

Bingo! Very stiff and supportive. The downside is they are somewhat clunky, but this is what I use, since I spend more time hiking in them than attempting to climb anything.

Make a rock plate for the TX4's: take the insole out, trace it on a empty gallon milk jug (or laundry detergent jug - a little thicker), cut that out, insert in between the shoe and in the insole. I usually just have one for the toebox of my shoe.

Did that trick when I did this. Also a good trick for other LS shoes that lack a rock plate (or even a full outsole) like the LS Helios.

I have the Garmont Dragontails (Goretex version) and have loved them for the application that you're talking about.  They took a bit of breaking in before they were completely comfortable, but even sized for 4th class/5.easy climbing, I haven't had issues with toe pain walking downhill or kicking steps in snow.  I bought a size 11, which is what I normally wear for street shoes, so I'd say they run a bit small (I wear a 44.5 TC Pro, with flat toes, if that's a more helpful reference point).  Your concern about the roominess of the toe box may be a problem -- they are definitely more snug in the toes than my TX3s.

I bought mine in Jan 2016 and have quite a few miles on them, including a half dozen CO 14ers, where I wore them for the rock plate, in lieu of a mountain runner or lightweight hiker.  They are a bit heavy in the pack on multi-pitch climbs and are not great on smoother slabs (like E-Rock, where I vastly prefer my TX3s), but I think you'd be happy with them for the type of terrain that you mentioned if you can live with the fit.
