Windows 10: How can I install only Patch Tuesday updates, not “C” and “D” Updates?
Unless there is a critical patch, I want to usually wait for 1-2 weeks, just in case there is a problem with the patches. But that means that if I update then I run more risks by downloading the "C” and “D” Updates.
Windows 10 Professional allows you to defer quality updates for up to 30 days. If you are worried about installing updates that have not been well tested you can defer updates to achieve this goal.
The only problem with deferring quality updates, is if a previous update has a known issue, you will eventually get that update after 30 days instead of the current update with the resolution. Any cumulative quality update has the potential to have a known issue like the last one for instance (KB4482887)
Is there any way (maybe a tool) to select which updates to download? The only one I can think of is by manually downloading each one, which is not very convenient?
You can configure your own WSUS environment, and only install the updates you push to your system, but that does not appear to be what you want to do. You can also disable Windows Update entirely and install updates manually.
If you want total control over your system, you will have to take the steps to prevent Windows Update from automatically downloading update entirely, and handle the entire process manually.

Stopping all automatic updates Windows 10
The article that you referenced already provides the answer:
Microsoft says C and D updates are “optional,” and Windows Update won’t automatically install them on your PC.
Windows Update doesn’t automatically install C and D updates on most PCs. However, it does install C and D updates when you head to Settings > Update & Security > Windows Update and click “Check for Updates.”
So, if you click “Check for Updates” in the third, fourth, or first week of a month before the next B update has been released, you’ll probably get a C or D update installed on your system. If you never click “Check for Updates,” you’ll stick with the better-tested B updates.
The bottom line is that if you don't manually initiate a search by utilizing the Check for updates button, you will get exactly what you desire: only the Patch Tuesday "B" updates will be installed automatically.
