requirement. As you are on Lion you will need to do an intermediate OS install. Mavericks is no longer available.
You can still get El Capitan (10.11.6) from here, How to upgrade to OS X El Capitan - Apple Support
go to Section 4 and click on Get Mac OS X El Capitan, this will download a .dmg file which you then

double-click to start the installation.
After El Capitan is installed then you can upgrade to Catalina, but if you are not aware yet Catalina does not run 32bit apps.
So I would suggest you install Mojave again and all the apps you would use, Upgrade to macOS Mojave - Official Apple Support
Once you have determined what apps you had previously on Mojave that were 32bit and whether or not the developers of those apps are updating them to 64bit then you can consider Catalina. Use this app, https://www.stclairsoft.com/Go64/ to check for 32bit apps.
