Here are five things I think beginners would really want to see:
1.  SQL Server as a new tool. Big-picture explanation, how it compares to Access, and when it makes sense to move to it.
2.Getting SQL Server up and running
Installing it, setting it up correctly, and understanding the basic tools without getting overwhelmed.
3.Core SQL skills that actually matter
Writing queries, joins, filtering, grouping—enough to be productive without assuming prior experience.
4.How people really use SQL Server in the real world
Common patterns, basic security concepts, and how data is typically organized and maintained.
5.Working with other tools (especially Access)
How SQL Server fits into an existing setup and how people commonly use it as a backend.

I think a beginner-friendly, practical approach would be really valuable, especially for people coming from Access or small-business environments.
