How do you usually do it when attaching two standing 95 studs, short side to short side? I'm going to extend a stud wall so that more insulation can fit. Right now, as I mentioned, it's just a framework. I have some theories myself, but there's surely a common method among carpenters.
Instead of placing the studs next to each other, you should offset the studs. You frame the wall using the 95 studs on a 190mm sill, then place studs between these but at the other edge of the sill. You will then have a 190mm wall but have broken the thermal bridges through the studs. You will, of course, not be able to use 190mm insulation but will need to use 95mm in both the inner and outer frameworks.
After that, you can nail the 45s lying on these as you planned. Keep in mind that any vapor barrier should be placed between the 95 studs and the 45 studs.

Before giving more tips on various ways to break the cold bridge, we should perhaps ask ourselves if the construction can manage with 45x95 in cc60 in the (load-bearing) outer walls. Is it a one or two-story building, what is the span and type of trusses, what snow zone, etc.
It is not at all impossible (I believe) that 45x95 can manage, especially if the trusses are bridged with a standing load-bearing beam under the ridge beam. But I think the question should be raised...
If you have strength requirements that require the cooperation of the two 45x95s, I don't dare to suggest any joining technique, as there may be some special forces that need to be addressed.
Otherwise, you might consider skew nailing or using nail plates (a few per stud). But since you asked about the common methods among carpenters, I really shouldn't try to answer...
Buying 195s instead, is that not worth considering?

It is the upper floor of a 1.5-story house in question. The construction is surely properly dimensioned for snow load, etc. My question is really about needing to extend the wall by an additional 95 + 45 to achieve the insulation thickness I need. I should have been clearer there. So my extension has nothing to do with the structural strength of the construction but is really just to provide space for more insulation and to support the plasterboard walls. Sorry! Now it might be easier to give tips.
The most common way to join two studs regardless of dimension is to nail on battens on both sides of... not on the short sides but on the flats.... The battens should be at least 30 cm long, preferably 40 cm... Between 8 and 12 nails on each side of the stud... So 4-6 nails in each piece/side...
Regarding thermal bridge in this case, it's not a problem since you will be applying plastic between 95 and 45... (Outer wall) ... and then using 95 and 45 insulation..

22X95 or 28x95 boards are sufficient for your case..
