I don't know the answer to your question, but regarding Fusion versions and macOS Compatibility:
- Fusion 12.0 through 12.1.2 run on macOS 10.15.x Catalina, so upgrading to Fusion 12 would allow you stay on the same macOS version as long as you download the installer for an older minor version of Fusion.
- Fusion 12.2.x requires macOS 11 Big Sur or macOS 12 Monterey.
- Fusion 13 requires macOS 12 Monterey or macOS 13 Ventura.
Fusion 12.0 thru 12.1.2 on Catalina is the last combination using VMware's hypervisor. Fusion 12.2 and later on Big Sur or later uses Apple's hypervisor, which changes several behavioural details and has some limitations in areas such as advanced networking and nested virtualisation (depending on the specific processor in your Mac).
Fusion 13 has been released and Fusion 12 is no longer being sold, but you can upgrade from Fusion 11 to 13, and it should be possible to downgrade the Fusion 13 licence to Fusion 12. I haven't tried that.
I also haven't heard confirmation yet whether a "free for personal use" Fusion 13 Player licence allows downgrade to Fusion 12 Player.
