Hey @TadesseAzagaw
You're in the right spot for all your answers!
In terms of joining the industry, coming from academics you're more than likely going to end up in some type of analyst role, a GIS Administrator role, or a supervisory role since you've got teaching experience and GIS has quite a lot that needs teaching. Your masters degree would count to some as years of experience, so you're in a decent spot already, I would look at your local community, and see if there is a need for a city GIS technician, or what I did was look at telecommunications companies, since they always need GIS technicians and administrators!
In terms of training, Esri has a very large amount of ArcGIS Pro and ArcGIS environment instructional documentation. This is all free to view and there are ways to get trial licenses to check out how things run, it's a large chance that the GIS position you'd find yourself in would be using ArcGIS or Esri software. Here's a link to the instructional document page: https://www.esri.com/en-us/arcgis/products/arcgis-pro/resources
