i want to remotely ssh to my home server, and I was wondering if I could just forward port 22 with disabling password login and use pubkey authentication will be safe enough?

As long as password auth is disabled you’re fine. No one is cracking your RSA key. You can add Fail2Ban to reduce the log noise, but security wise it’s fine.

Also don't use rsa, use Ed25519 nowadays

RSA is fine. It isn't like you will have to worry about the length of the keys for SSH.

It is but if you're going to use something security related, use the current recommendation unless you stricly can't for legacy reason or something.
