Aug 16, 2021 A preview of Mac OS X 10.7 Lion was publicly shown at the 'Back to the Mac' Apple Special Event on October 20, 2010. Mac Os X Mountain Lion Vs El Capitan; Is Mac Os X Mountain Lion Still Supported; Can I Update My Mac From Lion To El Capitan; Mac Os X Mountain Lion Upgrade To El Capitan; macOS Big Sur elevates the most advanced desktop.
In order to upgrade to the dizzying heights of Catalina your Mac must have Mac OS X Mavericks as its minimum OS
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.

OS X Version: Mountain Lion (10.8), most models. Mavericks (10.9) or higher — all models.
How to check it:
The number underneath 'OS X' is your version number.
If you're running a version of OS X older than 10.8, look into upgrading your OS X. Also, Apple notes that Metal is only available on 'all Macs since 2012'.
RAM: 4 GB (preferably 8 GB)
In the same menu you have the 'Memory' tab. If you have less than 4 GB RAM, you'll have to look into upgrading your RAM.
Disk Space: 15 GB to 20 GB of free space on drive
Next to 'Memory,' select 'Storage' tab. In front of the multi-colored bar, you will see the phrase, 'X.XX GB free out of XX.XX GB.' If you don't have at least 15 GB of free space, look into cleaning your Mac with cleanup tool, like CleanMyMac 3.
