HealthCare setup

I am currently on the Data Engineering Specialization course. I also work for an Oncology Hospital as support for the basic computer needs. Which is emails, a spreadsheet and support for the network and how to use their applications such as word and excel.
The center however wants to switch to cloud systems and the healthcare products that are available. As I am studying in the relevant field they have asked me to look into a system and how best to try it for the center. I have to be mindful that we are a small, but well run and renowned, Private treatment in Radiology and Chemotherapy currently with just over 3000 records, over the last 9 years. What would be the best place to start and any other advice?
