Ask HN: What selfhosted PaaS would you recommend?

I recently acquired a decently large server (512 GB ram, 64 cores), and am looking into self-hosting some web applications -- Invidious, file server, proxy, to name a few.

I was recommended Dokku[1], and after searching I also found several more similar products, like Coolify, DokDeploy, CapRover. I'm pretty new to doing this, so I would like to ask what experience you've had with these.
