Clean reinstall keeping data

I have my hackintosh for 2.5 years. I started with Sierra and upgraded over the years all the way to Catalina. I also installed and removed tonnes of different software. Now once in a while I see weird things happening. I suspect it's remnants of all that software interfering in subtle ways.

So how do I reinstall macOS clean but keep all my data, Clover, and Windows partition intact?

I'm currently on Catalina with APFS. I'm not very familiar with it. Here's my disk map:
