Repoint and Parge basement brick walls

I have a home that was built in 1939 and a basement that was previously finished in the 1970's. I have removed the walls because the prior owner had put insulation up against the brick walls. This led to some nice mold and wet insulation which I noticed after I moved in.

My basement was wet during the springtime when I bought the house, but I have since fixed issues outside (gutters, etc...), and it is dry. I do run a humidifier during the summer.

I would like to repair the brick walls and potentially finish the basement the right way. Are there any recommendations for a mortar mix for repointing the brickwork and then a mix for parging. I have seen alot of talk about older homes, but not so many for newer homes like my 1939 home.

What I have seen for homes built before 1930ish:
For repointing use a lime based mix, maybe 1:2:6 (portland :lime: sand)
Next parge over with a slightly softer and richer mix say 1:2.5:8.
Then use something like drylok to water seal the brick.

Any thoughts from those that may have done this before? A photo of the basement is attached. You can see it is a mix of painted brick, sections that were previously parged, and exposed brick.

Thank you both for the insights. I have had the house for about ten years, so I think the water problem is under control. I removed the walls when I first bought it, but am just getting around to the basement now. Good times all around.
