After Varta CR 1/2 AA

Like this one:

But not sure on these:

Nope - with three different brands, and capacities from 850mah to 1200mah these primary cells are all different. The two varta ones look different so is one fake?, and the 1200mah capacity is about what you get from a good panasonic.

There is a thread on CR123s and rechargeable substitutes here: https://budgetlightforum.com/t/-/20261

So if I want the CR 1/2, I could use a CR123?

I misread and thought CR123

No worries, I did find some more which are the right ones.

Hard to get tho.

Almost impossible to find in Australia for some reason.

Some of these have a different chemical make up.
Thionyl Chloride vs. Lithium, It looks like you are looking for standard Lithium.

I found this by searching:
“Another type of lithium cell having a large energy density is the lithium-thionyl chloride cell. Lithium-thionyl chloride batteries are generally not sold to the consumer market, and find more use in commercial/industrial applications, or are installed into devices where the consumer does not replace them.”

Also one battery you linked has solder tabs.

What are you using them in? Just curious.
