I have a 4GB Raspberry Pi 5 running Home Assistant and it's doing well.

For comparison, the Pi has a 4-core A76 processor while the CM3588 has 4 A76 cores plus another 4 A55 cores. I think it'll do fine.

Looks like that boat is ARM64, and min 4GB RAM, should be fine.

I'm running Proxmox on a mini PC. I have a Debian VM for streaming and a Home Assistant VM.

Runs like a dream

Yeah, you'll be okay. The easiest way is to pick a generic image for ARM here: https://github.com/home-assistant/operating-system/releases/latest and run with using Incus/LXD or some other virtualization solution that you like. I personally run it on Incus.

You can also do a more barebones manual install in a container if you don't want to run the entire thing. I would still stick with a Incus container or VM to avoid polluting your base system.
