If you're going to finish the basement, I suggest getting underway instead of stop gaps in the meantime.
Near same situation as us. I hung 6 mill plastic along the walls by rolling a few wraps around furring strips and driving tapco (?) masonry screws through the strips and into the wall. Then framed on 24" centers (non-bearing), wired for power, 4" fiberglass insulation and drywall. I laid 6 mill plastic on the floor sealed with 3M tape specifically made for plastic. Put underlayment on the plastic and a floating floor.
The plastic creates a vapor barrier and the insulation prevents condensation in summer high humidity.
I had replaced our hot water heater with a 75 gallon unit earlier. As I was finishing the basement, I noticed two plugged connections on the heater labeled "heat in" and "heat out". After some head scratching, I ran a loop of fin-tube along the two longest walls off those connections with pex pipe and domestic water circulator with an across the line stat. Despite everyone saying the water won't be hot enough to heat the basement, its the coziest place in the house.
I configured for a mini-split AC unit. Its been a couple years and the basement never went above 76 degrees even during the worst dog days of summer.
