How to setup access to VM instance with static ip through Google OAuth like Cloudflare Access?
Now I can setup access only for Service Account, Tags and some range of IP Addresses How it can be configured only for specific gmail-users?

Jan Hernandez already answered in a comment, however I still want to answer:
Identity Aware Proxy actually lets you perform what you are looking for, it's a GCP component that give you the option to restrict access to resources by access level, this can be done with gmail users as well, however you'll need to set up an OAuth consent screen.
Give it a look and try it.
