Would this not depend on your own requirements / constraints?
If you're looking for "the most recently released ROS 2 version on 20.04", then you have no choice but to install Galactic.
If you're looking for stability and LTS support, go with Foxy.
If you actually would like to use a newer release, use the Docker images of Humble and you wouldn't be limited by your host OS.

Edit:
Why the Galactic has shorter EOL than Foxy?
Because it's a non-LTS release:
Support
LTS releases
Since Ubuntu LTS releases come with 5 years of standard support we aim to match the same duration. In even years new ROS 2 releases will happen one month after the Ubuntu LTS has been released (which usually means a ROS 2 release in May). The ROS 2 release will be supported until the end of the standard support of the Ubuntu LTS release which is 4 years and 11 months from the ROS 2 release date.
Non-LTS Releases
In order to provide frequent releases to the community, in odd years a non-LTS ROS 2 release will be published. It will always target the same Ubuntu LTS as the previous ROS 2 LTS release but will only be supported for 1.5 years. This duration ensures that the non-LTS will overlap with the next ROS LTS release by 6 months to provide a long enough transition window.
Releases and support duration
- May 2021: G Turtle: non-LTS release, supported for 1.5 years
- May 2022: H Turtle: LTS release, supported for 5 years
- May 2023: I Turtle: non-LTS release, supported for 1.5 years
- May 2024: J Turtle: LTS release, supported for 5 years
- and so on, alternating annually between LTS and non-LTS releases
