It depends on the usage. I suggest to check out this page

Overall either Linux or Windows is OK to run Jira. As a experienced admin I personally prefer Linux (redhat/centos/debian is fine) since you can do more stuff than on Windows, but this depends on your personal (or admin) preferences. On both platforms it would be OK.

Over time you might need to scale. That is normal. If you add extensions, data would grow, more users would be using system then you would need to add more CPU and memory. But those are usually not big changes to the hardware. Overall start small and grow if needed.
