Server side cache is cleared.

Just cleared by browser cache and checked again but still see WP Rocket in the source code:

I'm going to guess that it's causing the problem you are experiencing as well.

Hi Leo,

I recreated this problem on my own hosting plan with zero plugins except GPP/GB, some fake content, same theme settings, GP elements copied over, and the Infinite Scroll works.

Deducing it is most likely WP Rocket, we may be better contacting their support team.

What are the top 3 cache plugins that cause the most issues for GeneratePress? And do you recommend any alternatives to WP Rocket that create less support ticket?

All of them should be compatible with GeneratePress. There are usually some settings within caching plugins that might cause some issues depending on what GP features you are using but you can test by toggling the options on and off.

And do you recommend any alternatives to WP Rocket that create less support ticket?

We only use Autopimize ourselves:
