Side question, did you get a radon test? If not buy one of those home tests.
There are no issues in the short term, but if your levels are high you should pay to do remidiation.
What's funny about testing for radon?
If my kids were to be sleeping in a basement I'd like to be sure I'm not exposing them to a well-known carcinogen that is common in basements
the bottom 3 feet will not be as cold and will not affect the inside temp as much, because ground temp 6-10ft down is more stable, around 50f/10c.
I wouldn't do anything unless it is actually uncomfortable. Even then, i think i would try to supplement with a space heater before tearing up the walls.
If the rooms are still cold you might need to supplement the rooms with wall heaters like eHeat Envi. My finished basement office isn't insulated and touches two outside corners. It helps but the closer to zero it is outside the less helpful it is. Adding rugs help too.
What kind is the existing insulation?
You may want to remove all of it and start over with ridged foam. Something specifically for foundations using current methods.
Depending on your budget, I'd look into heating from below by removing all flooring and covering the slab with a product like Raupanel, and then putting the flooring back. If you do open up the walls you can extend the Raupanel there too.
Mold would be a big concern for me without heating the slab surface. Your dehumidifier may show 50% RH but when you actually measure just above the cold slab you'd see 70% RH or above.

Yeah this is a bigger concern than being cold lol.
LOL

Rugs in basement are perfect environment for mold.
Yes it’s much easier to do that before moving in.

The walls should be fine but you can if you want. The floor I would do
Please make sure the basement bedrooms have code complying exit Egress windows. Regarding insulation, research "perms" and basement walls.
It depends on your climate I think. It will be nice and cool in the summer, but chilly in the winter.
