What is the best way to access apps locally on a linode?

I installed grafana and few monitoring tools locally on a linode. For security reasons, we have disabled remote access to this server (hence why I went with the local installation instead of cloud connection).

At first, I did some port forwarding and started visiting localhost:<port-number> on my local machine, but realized this may not be the safest way to do this.</port-number>

Theoretically speaking, what is the best and most secure way to be able to run apps locally and access them from a remote machine?

I tried VPCs, but apparently the linode needs to be in a region that is supported by the VPC.

Thank you.
