At 2018 WWDC, Apple officially announced that macOS Mojave is the last version of maOS to support 32-bit apps. Though 32-bit apps can run on macOS High Sierra, you would constantly receive the warnning to let you update apps or optimize apps to improve compatibility. So far, it's unclear what you'll be asked to do if 32-bit apps work on your macOS Big Sur computer. But what is confirmed is that 32-bit apps are entirely excluded starting with the next year's macOS release.
Among your varied macOS apps, DVD ripper might be your most concern, for majority of DVD copy programs are 32-bit apps. Fortunately, after a lot of searches and test I have done, I find that there are still some 64-bit DVD ripping programs that can rip and copy DVD on macOS Big Sur or later perfectly without update or optimization requirements. MacX DVD Ripper Pro is just one of them.
