How to compare and MERGE two SQL Server environments (not just databases)

Question

Many similar questions were asked before, and mostly about comparing database schemas and data. That's all fine, but what about all the other SQL Server objects in the system overall?

This is the closest answer I've found, but it doesn't answer my query on a tool to be able to also create an SQL script of the variances, that can be easily applied to another server - including new user logins, roles, schemas, linked-servers, maps, maintenance plans, etc.

The other tool I found that does this is TOAD for SQL Server, but it's not cheap. I was hoping for an SQL script solution? Particularly with a mix of SQL Server environments from 2008 R2 to 2017?

Thanks
