For my buildings I use Type O when it's just patching empty joints. It cleans up better and is super easy to work with. If there lintel work, rebuilding, grind and point, then yeah, N is probably better because it's a bit stronger and you want to really glue any bricks you loosened up tightly in place. O is nice because you can just smash it into the joints and still broom it off 30 min later.

Sorry to revisit this topic again, but a preservation-minded neighbor just stirred the pot by steering me away from Type O/N mortars, introducing me to Hydraulic Lime mortars. Referenced this site:
https://hfsmaterials.com/restoration...e-mortar-tips/
Purportedly, the Naturally Hydraulic Lime (NHL) products are breathable enough to release moisture and eliminate effervescence.
Is going this route more than what is necessary, especially if it's unlikely that a building doesn't currently use an NHL mortar?
I can't wait to hear from all the experts here.
