In brief, I'm using a secure endpoint connection (EC2 instance connect) that allows only ports 22 and 3389. Is port 22 safe, considering its common use as a connection port?

"I am utilizing the secure endpoint connection (EC2 instance connect), and the documentation specifies that only ports 22 and 3389 are allowed. My question is whether port 22 is secure because it's a commonly used connection port.

Port 22 is the designated port for SSH. You should focus more on who is allowed to connect via that port. Example: 0.0.0.0/0 will allow everyone to exploit that connect, so be mindful on which IP you use. Moreover, use IAM policies and the likes to enforce it: https://aws.amazon.com/blogs/security/use-ec2-instance-connect-to-provide-secure-ssh-access-to-ec2-instances-with-private-ip-addresses/
