Go to Utilities>System Information. Click on Applications. When the list comes up click on 64-Bit column. This will show all 32-Bit apps. If you use any of them on an ongoing basis then DON'T upgrade to Catalina. If those apps have newer versions that are compatible with Catalina and you don't mind spending a few $ on them then it's your call as to upgrade or not. Hope the helps.
