I often covet the basements I see on homesteading Youtube channels but then I remember I have been in your situation in more than one home. It is a real challenge to fix. I opted to leave one basement bare as it was a rented house and the water/moisture caused the main floor carpet pads to mold. I pulled the carpets to dry on the
fence which ticked off the landlord. It was a beaver dam that directed the stream into the basement that time. I had my office in the basement complete with digitizing table, drafting table and computers. I had hung cords from rafters and all furniture was propped up on cinder blocks but the
water was much deeper. And the many
mice I shared space with had left the building til things were dried out. We were told it could not be fixed. So we moved. The next one was a finished basement. A crack in the corner of the egress window allowed the water in. Sheetrock and flooring destroyed. I opted to replace the sheetrock once the crack was grouted and a better French drain was built but i just stuck with painting a rubberized cement paint on the floor and added colorful rugs. I agree that leaving things less finished but painted makes the repairs easy and being able to see the issue faster if there is a next time. Anything that does not mold but likes humidity like the mentioned canning jar storage, plants etc. Would be great. I had a second woodstove down there so i could help things dry out faster than with fans alone. I have seen many people turn the cold corner of the basement into a separate cold storage room which would be a dream for me. Ventilation is key regardless so the moisture and mold can be managed. Mold is usually the issue I dealt with when i had a basement. I wouldnt sleep down there due to allergies but it was nice and cool in summer so keeping yours as a livable space is a great plan. Best wishes!
